[javascript] Add table row in jQuery

What is the best method in jQuery to add an additional row to a table as the last row?

Is this acceptable?

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

Are there limitations to what you can add to a table like this (such as inputs, selects, number of rows)?

Add tabe row using JQuery:

if you want to add row after last of table's row child, you can try this

$('#myTable tr:last').after('<tr>...</tr><tr>...</tr>');

if you want to add row 1st of table's row child, you can try this

$('#myTable tr').after('<tr>...</tr><tr>...</tr>');

This could also be done :

$("#myTable > tbody").html($("#myTable > tbody").html()+"<tr><td>my data</td><td>more data</td></tr>")

For the best solution posted here, if there's a nested table on the last row, the new row will be added to the nested table instead of the main table. A quick solution (considering tables with/without tbody and tables with nested tables):

function add_new_row(table, rowcontent) {
    if ($(table).length > 0) {
        if ($(table + ' > tbody').length == 0) $(table).append('<tbody />');
        ($(table + ' > tr').length > 0) ? $(table).children('tbody:last').children('tr:last').append(rowcontent): $(table).children('tbody:last').append(rowcontent);
    }
}

Usage example:

add_new_row('#myTable','<tr><td>my new row</td></tr>');

Neil's answer is by far the best one. However things get messy really fast. My suggestion would be to use variables to store elements and append them to the DOM hierarchy.

HTML

<table id="tableID">
    <tbody>
    </tbody>
</table>

JAVASCRIPT

// Reference to the table body
var body = $("#tableID").find('tbody');

// Create a new row element
var row = $('<tr>');

// Create a new column element
var column = $('<td>');

// Create a new image element
var image = $('<img>');
image.attr('src', 'img.png');
image.text('Image cell');

// Append the image to the column element
column.append(image);
// Append the column to the row element
row.append(column);
// Append the row to the table body
body.append(row);

In my opinion the fastest and clear way is

//Try to get tbody first with jquery children. works faster!
var tbody = $('#myTable').children('tbody');

//Then if no tbody just select your table 
var table = tbody.length ? tbody : $('#myTable');

//Add row
table.append('<tr><td>hello></td></tr>');

here is demo Fiddle

Also I can recommend a small function to make more html changes

//Compose template string
String.prototype.compose = (function (){
var re = /\{{(.+?)\}}/g;
return function (o){
        return this.replace(re, function (_, k){
            return typeof o[k] != 'undefined' ? o[k] : '';
        });
    }
}());

If you use my string composer you can do this like

var tbody = $('#myTable').children('tbody');
var table = tbody.length ? tbody : $('#myTable');
var row = '<tr>'+
    '<td>{{id}}</td>'+
    '<td>{{name}}</td>'+
    '<td>{{phone}}</td>'+
'</tr>';


//Add row
table.append(row.compose({
    'id': 3,
    'name': 'Lee',
    'phone': '123 456 789'
}));

Here is demo Fiddle

As i have also got a way too add row at last or any specific place so i think i should also share this:

First find out the length or rows:

var r=$("#content_table").length;

and then use below code to add your row:

$("#table_id").eq(r-1).after(row_html);

This is my solution

$('#myTable').append('<tr><td>'+data+'</td><td>'+other data+'</td>...</tr>');

    // Create a row and append to table
    var row = $('<tr />', {})
        .appendTo("#table_id");

    // Add columns to the row. <td> properties can be given in the JSON
    $('<td />', {
        'text': 'column1'
    }).appendTo(row);

    $('<td />', {
        'text': 'column2',
        'style': 'min-width:100px;'
    }).appendTo(row);

You can use this great jQuery add table row function. It works great with tables that have <tbody> and that don't. Also it takes into the consideration the colspan of your last table row.

Here is an example usage:

// One table
addTableRow($('#myTable'));
// add table row to number of tables
addTableRow($('.myTables'));

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

will add a new row to the first TBODY of the table, without depending of any THEAD or TFOOT present. (I didn't find information from which version of jQuery .append() this behavior is present.)

You may try it in these examples:

<table class="t"> <!-- table with THEAD, TBODY and TFOOT -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
<tbody>
  <tr><td>1</td><td>2</td></tr>
</tbody>
<tfoot>
  <tr><th>f1</th><th>f2</th></tr>
</tfoot>
</table><br>

<table class="t"> <!-- table with two TBODYs -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
<tbody>
  <tr><td>1</td><td>2</td></tr>
</tbody>
<tbody>
  <tr><td>3</td><td>4</td></tr>
</tbody>
<tfoot>
  <tr><th>f1</th><th>f2</th></tr>
</tfoot>
</table><br>

<table class="t">  <!-- table without TBODY -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
</table><br>

<table class="t">  <!-- table with TR not in TBODY  -->
  <tr><td>1</td><td>2</td></tr>
</table>
<br>
<table class="t">
</table>

<script>
$('.t').append('<tr><td>a</td><td>a</td></tr>');
</script>

In which example a b row is inserted after 1 2, not after 3 4 in second example. If the table were empty, jQuery creates TBODY for a new row.

For the best solution posted here, if there's a nested table on the last row, the new row will be added to the nested table instead of the main table. A quick solution (considering tables with/without tbody and tables with nested tables):

function add_new_row(table, rowcontent) {
    if ($(table).length > 0) {
        if ($(table + ' > tbody').length == 0) $(table).append('<tbody />');
        ($(table + ' > tr').length > 0) ? $(table).children('tbody:last').children('tr:last').append(rowcontent): $(table).children('tbody:last').append(rowcontent);
    }
}

Usage example:

add_new_row('#myTable','<tr><td>my new row</td></tr>');

Add tabe row using JQuery:

if you want to add row after last of table's row child, you can try this

$('#myTable tr:last').after('<tr>...</tr><tr>...</tr>');

if you want to add row 1st of table's row child, you can try this

$('#myTable tr').after('<tr>...</tr><tr>...</tr>');

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

Write with a javascript function

document.getElementById("myTable").insertRow(-1).innerHTML = '<tr>...</tr><tr>...</tr>';

What if you had a <tbody> and a <tfoot>?

Such as:

<table>
    <tbody>
        <tr><td>Foo</td></tr>
    </tbody>
    <tfoot>
        <tr><td>footer information</td></tr>
    </tfoot>
</table>

Then it would insert your new row in the footer - not to the body.

Hence the best solution is to include a <tbody> tag and use .append, rather than .after.

$("#myTable > tbody").append("<tr><td>row content</td></tr>");

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

Write with a javascript function

document.getElementById("myTable").insertRow(-1).innerHTML = '<tr>...</tr><tr>...</tr>';

jQuery has a built-in facility to manipulate DOM elements on the fly.

You can add anything to your table like this:

$("#tableID").find('tbody')
    .append($('<tr>')
        .append($('<td>')
            .append($('<img>')
                .attr('src', 'img.png')
                .text('Image cell')
            )
        )
    );

The $('<some-tag>') thing in jQuery is a tag object that can have several attr attributes that can be set and get, as well as text, which represents the text between the tag here: <tag>text</tag>.

This is some pretty weird indenting, but it's easier for you to see what's going on in this example.

This could also be done :

$("#myTable > tbody").html($("#myTable > tbody").html()+"<tr><td>my data</td><td>more data</td></tr>")

I recommend

$('#myTable > tbody:first').append('<tr>...</tr><tr>...</tr>'); 

as opposed to

$('#myTable > tbody:last').append('<tr>...</tr><tr>...</tr>'); 

The first and last keywords work on the first or last tag to be started, not closed. Therefore, this plays nicer with nested tables, if you don't want the nested table to be changed, but instead add to the overall table. At least, this is what I found.

<table id=myTable>
  <tbody id=first>
    <tr><td>
      <table id=myNestedTable>
        <tbody id=last>
        </tbody>
      </table>
    </td></tr>
  </tbody>
</table>

What if you had a <tbody> and a <tfoot>?

Such as:

<table>
    <tbody>
        <tr><td>Foo</td></tr>
    </tbody>
    <tfoot>
        <tr><td>footer information</td></tr>
    </tfoot>
</table>

Then it would insert your new row in the footer - not to the body.

Hence the best solution is to include a <tbody> tag and use .append, rather than .after.

$("#myTable > tbody").append("<tr><td>row content</td></tr>");

I have tried the most upvoted one, but it did not work for me, but below works well.

$('#mytable tr').last().after('<tr><td></td></tr>');

Which will work even there is a tobdy there.

If you want to add row before the <tr> first child.

$("#myTable > tbody").prepend("<tr><td>my data</td><td>more data</td></tr>");

If you want to add row after the <tr> last child.

$("#myTable > tbody").append("<tr><td>my data</td><td>more data</td></tr>");

To add a new row at the last of current row, you can use like this

$('#yourtableid tr:last').after('<tr>...</tr><tr>...</tr>');

You can append multiple row as above. Also you can add inner data as like

$('#yourtableid tr:last').after('<tr><td>your data</td></tr>');

in another way you can do like this

let table = document.getElementById("tableId");

let row = table.insertRow(1); // pass position where you want to add a new row


//then add cells as you want with index
let cell0 = row.insertCell(0);
let cell1 = row.insertCell(1);
let cell2 = row.insertCell(2);
let cell3 = row.insertCell(3);


//add value to added td cell
 cell0.innerHTML = "your td content here";
 cell1.innerHTML = "your td content here";
 cell2.innerHTML = "your td content here";
 cell3.innerHTML = "your td content here";

In a simple way:

$('#yourTableId').append('<tr><td>your data1</td><td>your data2</td><td>your data3</td></tr>');

If you are using Datatable JQuery plugin you can try.

oTable = $('#tblStateFeesSetup').dataTable({
            "bScrollCollapse": true,
            "bJQueryUI": true,
            ...
            ...
            //Custom Initializations.
            });

//Data Row Template of the table.
var dataRowTemplate = {};
dataRowTemplate.InvoiceID = '';
dataRowTemplate.InvoiceDate = '';
dataRowTemplate.IsOverRide = false;
dataRowTemplate.AmountOfInvoice = '';
dataRowTemplate.DateReceived = '';
dataRowTemplate.AmountReceived = '';
dataRowTemplate.CheckNumber = '';

//Add dataRow to the table.
oTable.fnAddData(dataRowTemplate);

Refer Datatables fnAddData Datatables API

I'm using this way when there is not any row in the table, as well as, each row is quite complicated.

style.css:

...
#templateRow {
  display:none;
}
...

xxx.html

...
<tr id="templateRow"> ... </tr>
...

$("#templateRow").clone().removeAttr("id").appendTo( $("#templateRow").parent() );

...

The answers above are very helpful, but when student refer this link to add data from form they often require a sample.

I want to contribute an sample get input from from and use .after() to insert tr to table using string interpolation.

function add(){
  let studentname = $("input[name='studentname']").val();
  let studentmark = $("input[name='studentmark']").val();

  $('#student tr:last').after(`<tr><td>${studentname}</td><td>${studentmark}</td></tr>`);
}

function add(){_x000D_
let studentname = $("input[name='studentname']").val();_x000D_

Here is some hacketi hack code. I wanted to maintain a row template in an HTML page. Table rows 0...n are rendered at request time, and this example has one hardcoded row and a simplified template row. The template table is hidden, and the row tag must be within a valid table or browsers may drop it from the DOM tree. Adding a row uses counter+1 identifier, and the current value is maintained in the data attribute. It guarantees each row gets unique URL parameters.

I have run tests on Internet Explorer 8, Internet Explorer 9, Firefox, Chrome, Opera, Nokia Lumia 800, Nokia C7 (with Symbian 3), Android stock and Firefox beta browsers.

<table id="properties">
<tbody>
  <tr>
    <th>Name</th>
    <th>Value</th>
    <th>&nbsp;</th>
  </tr>
  <tr>
    <td nowrap>key1</td>
    <td><input type="text" name="property_key1" value="value1" size="70"/></td>
    <td class="data_item_options">
       <a class="buttonicon" href="javascript:deleteRow()" title="Delete row" onClick="deleteRow(this); return false;"></a>
    </td>
  </tr>

PS: I give all credits to the jQuery team; they deserve everything. JavaScript programming without jQuery - I don't even want think about that nightmare.

I Guess i have done in my project , here it is:

html

<div class="container">
    <div class = "row">
    <div class = "span9">
        <div class = "well">
          <%= form_for (@replication) do |f| %>
    <table>
    <tr>
      <td>
          <%= f.label :SR_NO %>
      </td>
      <td>
          <%= f.text_field :sr_no , :id => "txt_RegionName" %>
      </td>
    </tr>
    <tr>

js

$(document).ready(function() {     
    $('#submit').prop('disabled', true);
    $('#btn_AddToList').click(function () {
     $('#submit').prop('disabled', true);
    var val = $('#txt_RegionName').val();
    var val2 = $('#txt_Region').val();
    var val3 = $('#txt_Regio').val();
    var val4 = $('#txt_Regi').val();
    $('#lst_Regions').append('<tr><td>' + val + '</td>' + '<td>' + val2 + '</td>' + '<td>' + val3 + '</td>' + '<td>' + val4 + '</td></tr>');
    $('#txt_RegionName').val('').focus();
    $('#txt_Region').val('');
        $('#txt_Regio').val('');
        $('#txt_Regi').val('');
    $('#btn_AddToList1').click(function () {
         $('#submit').prop('disabled', false).addclass('btn btn-warning');
    });
      });
});

I solved it this way.

Using jquery

$('#tab').append($('<tr>')
    .append($('<td>').append("text1"))
    .append($('<td>').append("text2"))
    .append($('<td>').append("text3"))
    .append($('<td>').append("text4"))
  )

  .append($('<td>').append("text1"))_x000D_
  .append($('<td>').append("text2"))_x000D_
  .append($('<td>').append("text3"))_x000D_
  .append($('<td>').append("text4"))_x000D_

I found this AddRow plugin quite useful for managing table rows. Though, Luke's solution would be the best fit if you just need to add a new row.

To add a good example on the topic, here is working solution if you need to add a row at specific position.

The extra row is added after the 5th row, or at the end of the table if there are less then 5 rows.

var ninja_row = $('#banner_holder').find('tr');

if( $('#my_table tbody tr').length > 5){
    $('#my_table tbody tr').filter(':nth-child(5)').after(ninja_row);
}else{
    $('#my_table tr:last').after(ninja_row);
}

I put the content on a ready (hidden) container below the table ..so if you(or the designer) have to change it is not required to edit the JS.

<table id="banner_holder" style="display:none;"> 
    <tr>
        <td colspan="3">
            <div class="wide-banner"></div>
        </td>   
    </tr> 
</table>

To add a new row at the last of current row, you can use like this

$('#yourtableid tr:last').after('<tr>...</tr><tr>...</tr>');

You can append multiple row as above. Also you can add inner data as like

$('#yourtableid tr:last').after('<tr><td>your data</td></tr>');

in another way you can do like this

let table = document.getElementById("tableId");

let row = table.insertRow(1); // pass position where you want to add a new row


//then add cells as you want with index
let cell0 = row.insertCell(0);
let cell1 = row.insertCell(1);
let cell2 = row.insertCell(2);
let cell3 = row.insertCell(3);


//add value to added td cell
 cell0.innerHTML = "your td content here";
 cell1.innerHTML = "your td content here";
 cell2.innerHTML = "your td content here";

You can append it to the tbody using the appendTo method like this:

$(() => {
   $("<tr><td>my data</td><td>more data</td></tr>").appendTo("tbody");
});

You'll probably want to use the latest JQuery and ECMAScript. Then you can use a back-end language to add your data to the table. You can also wrap it in a variable like so:

$(() => {
  var t_data = $('<tr><td>my data</td><td>more data</td></tr>');
  t_data.appendTo('tbody');
});

<tr id="tablerow"></tr>

$('#tablerow').append('<tr>...</tr><tr>...</tr>');

So things have changed ever since @Luke Bennett answered this question. Here is an update.

jQuery since version 1.4(?) automatically detects if the element you are trying to insert (using any of the append(), prepend(), before(), or after() methods) is a <tr> and inserts it into the first <tbody> in your table or wraps it into a new <tbody> if one doesn't exist.

So yes your example code is acceptable and will work fine with jQuery 1.4+. ;)

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

    // Create a row and append to table
    var row = $('<tr />', {})
        .appendTo("#table_id");

    // Add columns to the row. <td> properties can be given in the JSON
    $('<td />', {
        'text': 'column1'
    }).appendTo(row);

    $('<td />', {
        'text': 'column2',
        'style': 'min-width:100px;'
    }).appendTo(row);

I know you have asked for a jQuery method. I looked a lot and find that we can do it in a better way than using JavaScript directly by the following function.

tableObject.insertRow(index)

index is an integer that specifies the position of the row to insert (starts at 0). The value of -1 can also be used; which result in that the new row will be inserted at the last position.

This parameter is required in Firefox and Opera, but it is optional in Internet Explorer, Chrome and Safari.

If this parameter is omitted, insertRow() inserts a new row at the last position in Internet Explorer and at the first position in Chrome and Safari.

It will work for every acceptable structure of HTML table.

The following example will insert a row in last (-1 is used as index):

<html>
    <head>
        <script type="text/javascript">
        function displayResult()
        {
            document.getElementById("myTable").insertRow(-1).innerHTML = '<td>1</td><td>2</td>';
        }
        </script>
    </head>

    <body>       
        <table id="myTable" border="1">
            <tr>
                <td>cell 1</td>
                <td>cell 2</td>
            </tr>
            <tr>
                <td>cell 3</td>
                <td>cell 4</td>
            </tr>
        </table>
        <br />
        <button type="button" onclick="displayResult()">Insert new row</button>            
    </body>
</html>

I hope it helps.

<table id=myTable>
    <tr><td></td></tr>
    <style="height=0px;" tfoot></tfoot>
</table>

You can cache the footer variable and reduce access to DOM (Note: may be it will be better to use a fake row instead of footer).

var footer = $("#mytable tfoot")
footer.before("<tr><td></td></tr>")

So things have changed ever since @Luke Bennett answered this question. Here is an update.

jQuery since version 1.4(?) automatically detects if the element you are trying to insert (using any of the append(), prepend(), before(), or after() methods) is a <tr> and inserts it into the first <tbody> in your table or wraps it into a new <tbody> if one doesn't exist.

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

Try this : very simple way

$('<tr><td>3</td></tr><tr><td>4</td></tr>').appendTo("#myTable tbody");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_

I Guess i have done in my project , here it is:

      </td>
      <td>
          <%= f.text_field :sr_no , :id => "txt_RegionName" %>

      </td>
      <td>
        <%= f.text_field :quantity ,:id => "txt_Regi" %>
      </td>
    </tr>
    <tr>
    <td></td>
    <td>
    <table>
    <tr><td>
    <input type="button"  name="add" id="btn_AddToList" value="add" class="btn btn-primary" />
    </td><td><input type="button"  name="Done" id="btn_AddToList1" value="Done" class="btn btn-success" />
    </td></tr>
    </table>
    </td>
    </tr>
    </table>
    <% end %>
    <table id="lst_Regions" style="width: 500px;" border= "2" class="table table-striped table-bordered table-condensed">
    <tr>
    <td>SR_NO</td>
    <td>Item Name</td>
    <td>Particular</td>
    <td>Cost</td>
    </tr>
    </table>
    <input type="button" id= "submit" value="Submit Repication"  class="btn btn-success" />
    </div>
    </div>
    </div>
</div>

js

$(document).ready(function() {     
    $('#submit').prop('disabled', true);
    $('#btn_AddToList').click(function () {
     $('#submit').prop('disabled', true);
    var val = $('#txt_RegionName').val();
    var val2 = $('#txt_Region').val();
    var val3 = $('#txt_Regio').val();
    var val4 = $('#txt_Regi').val();
    $('#lst_Regions').append('<tr><td>' + val + '</td>' + '<td>' + val2 + '</td>' + '<td>' + val3 + '</td>' + '<td>' + val4 + '</td></tr>');
    $('#txt_RegionName').val('').focus();
    $('#txt_Region').val('');
        $('#txt_Regio').val('');
        $('#txt_Regi').val('');
    $('#btn_AddToList1').click(function () {
         $('#submit').prop('disabled', false).addclass('btn btn-warning');
    });
      });
});

I recommend

$('#myTable > tbody:first').append('<tr>...</tr><tr>...</tr>'); 

as opposed to

$('#myTable > tbody:last').append('<tr>...</tr><tr>...</tr>'); 

The first and last keywords work on the first or last tag to be started, not closed. Therefore, this plays nicer with nested tables, if you don't want the nested table to be changed, but instead add to the overall table. At least, this is what I found.

<table id=myTable>
  <tbody id=first>
    <tr><td>
      <table id=myNestedTable>
        <tbody id=last>
        </tbody>
      </table>
    </td></tr>
  </tbody>
</table>

My solution:

//Adds a new table row
$.fn.addNewRow = function (rowId) {
    $(this).find('tbody').append('<tr id="' + rowId + '"> </tr>');
};

usage:

$('#Table').addNewRow(id1);

<table id=myTable>
    <tr><td></td></tr>
    <style="height=0px;" tfoot></tfoot>
</table>

You can cache the footer variable and reduce access to DOM (Note: may be it will be better to use a fake row instead of footer).

var footer = $("#mytable tfoot")
footer.before("<tr><td></td></tr>")

Here, You can Just Click on button then you will get Output. When You Click on Add row button then one more row Added.

I hope It is very helpful.

                <td>cell 4</td>
            </tr>
        </table>
        <br />
        <button type="button" onclick="displayResult()">Insert new row</button>            
    </body>
</html>

I hope it helps.

To add a good example on the topic, here is working solution if you need to add a row at specific position.

The extra row is added after the 5th row, or at the end of the table if there are less then 5 rows.

var ninja_row = $('#banner_holder').find('tr');

if( $('#my_table tbody tr').length > 5){
    $('#my_table tbody tr').filter(':nth-child(5)').after(ninja_row);
}else{
    $('#my_table tr:last').after(ninja_row);
}

I put the content on a ready (hidden) container below the table ..so if you(or the designer) have to change it is not required to edit the JS.

<table id="banner_holder" style="display:none;"> 
    <tr>
        <td colspan="3">
            <div class="wide-banner"></div>
        </td>   
    </tr> 
</table>

This can be done easily using the "last()" function of jQuery.

$("#tableId").last().append("<tr><td>New row</td></tr>");

<tr id="tablerow"></tr>

$('#tablerow').append('<tr>...</tr><tr>...</tr>');

As i have also got a way too add row at last or any specific place so i think i should also share this:

First find out the length or rows:

var r=$("#content_table").length;

and then use below code to add your row:

$("#table_id").eq(r-1).after(row_html);

If you want to add row before the <tr> first child.

$("#myTable > tbody").prepend("<tr><td>my data</td><td>more data</td></tr>");

If you want to add row after the <tr> last child.

$("#myTable > tbody").append("<tr><td>my data</td><td>more data</td></tr>");

Try this : very simple way

$('<tr><td>3</td></tr><tr><td>4</td></tr>').appendTo("#myTable tbody");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
<table id="myTable">_x000D_
  <tbody>_x000D_
    <tr><td>1</td></tr>_x000D_
    <tr><td>2</td></tr>_x000D_
  </tbody>_x000D_
</table>

I solved it this way.

Using jquery

$('#tab').append($('<tr>')
    .append($('<td>').append("text1"))
    .append($('<td>').append("text2"))
    .append($('<td>').append("text3"))
    .append($('<td>').append("text4"))
  )

Snippet

$('#tab').append($('<tr>')_x000D_
  .append($('<td>').append("text1"))_x000D_
  .append($('<td>').append("text2"))_x000D_
  .append($('<td>').append("text3"))_x000D_
  .append($('<td>').append("text4"))_x000D_
)

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<table id="tab">_x000D_
  <tr>_x000D_
    <th>Firstname</th>_x000D_
    <th>Lastname</th> _x000D_
    <th>Age</th>_x000D_
    <th>City</th>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Jill</td>_x000D_
    <td>Smith</td> _x000D_
    <td>50</td>_x000D_
    <td>New York</td>_x000D_
  </tr>_x000D_
</table>

I was having some related issues, trying to insert a table row after the clicked row. All is fine except the .after() call does not work for the last row.

$('#traffic tbody').find('tr.trafficBody).filter(':nth-child(' + (column + 1) + ')').after(insertedhtml);

I landed up with a very untidy solution:

create the table as follows (id for each row):

<tr id="row1"> ... </tr>
<tr id="row2"> ... </tr>
<tr id="row3"> ... </tr>

etc ...

and then :

$('#traffic tbody').find('tr.trafficBody' + idx).after(html);

This can be done easily using the "last()" function of jQuery.

$("#tableId").last().append("<tr><td>New row</td></tr>");

if you have another variable you can access in <td> tag like that try.

This way I hope it would be helpful

var table = $('#yourTableId');
var text  = 'My Data in td';
var image = 'your/image.jpg'; 
var tr = (
  '<tr>' +
    '<td>'+ text +'</td>'+
    '<td>'+ text +'</td>'+
    '<td>'+
      '<img src="' + image + '" alt="yourImage">'+
    '</td>'+
  '</tr>'
);

$('#yourTableId').append(tr);

I have tried the most upvoted one, but it did not work for me, but below works well.

$('#mytable tr').last().after('<tr><td></td></tr>');

Which will work even there is a tobdy there.

TIP: Inserting rows in html table via innerHTML or .html() is not valid in some browsers (similar IE9), and using .append("<tr></tr>") is not good suggestion in any browser. best and fastest way is using the pure javascript codes.

for combine this way with jQuery, only add new plugin similar this to jQuery:

$.fn.addRow=function(index/*-1: add to end  or  any desired index*/, cellsCount/*optional*/){
    if(this[0].tagName.toLowerCase()!="table") return null;
    var i=0, c, r = this[0].insertRow((index<0||index>this[0].rows.length)?this[0].rows.length:index);
    for(;i<cellsCount||0;i++) c = r.insertCell(); //you can use c for set its content or etc
    return $(r);
};

And now use it in whole the project similar this:

var addedRow = $("#myTable").addRow(-1/*add to end*/, 2);

Pure JS is quite short in your case

myTable.firstChild.innerHTML += '<tr><td>my data</td><td>more data</td></tr>'

function add() {_x000D_
  myTable.firstChild.innerHTML+=`<tr><td>date</td><td>${+new Date}</td></tr>`_x000D_
}

td {border: 1px solid black;}

<button onclick="add()">Add</button><br>_x000D_
<table id="myTable"><tbody></tbody> </table>

(if we remove <tbody> and firstChild it will also works but wrap every row with <tbody>)

My solution:

//Adds a new table row
$.fn.addNewRow = function (rowId) {
    $(this).find('tbody').append('<tr id="' + rowId + '"> </tr>');
};

usage:

$('#Table').addNewRow(id1);

You can use this great jQuery add table row function. It works great with tables that have <tbody> and that don't. Also it takes into the consideration the colspan of your last table row.

Here is an example usage:

// One table
addTableRow($('#myTable'));
// add table row to number of tables
addTableRow($('.myTables'));

Here, You can Just Click on button then you will get Output. When You Click on Add row button then one more row Added.

I hope It is very helpful.

I want to contribute an sample get input from from and use .after() to insert tr to table using string interpolation.

function add(){
  let studentname = $("input[name='studentname']").val();

    <th>Mark</th>_x000D_
  </thead>_x000D_
</table>_x000D_
</body>_x000D_
</html>

Pure JS is quite short in your case

myTable.firstChild.innerHTML += '<tr><td>my data</td><td>more data</td></tr>'

function add() {_x000D_
  myTable.firstChild.innerHTML+=`<tr><td>date</td><td>${+new Date}</td></tr>`_x000D_
}

td {border: 1px solid black;}

<button onclick="add()">Add</button><br>_x000D_
<table id="myTable"><tbody></tbody> </table>

(if we remove <tbody> and firstChild it will also works but wrap every row with <tbody>)

jQuery has a built-in facility to manipulate DOM elements on the fly.

You can add anything to your table like this:

$("#tableID").find('tbody')
    .append($('<tr>')
        .append($('<td>')
            .append($('<img>')
                .attr('src', 'img.png')
                .text('Image cell')
            )
        )
    );

The $('<some-tag>') thing in jQuery is a tag object that can have several attr attributes that can be set and get, as well as text, which represents the text between the tag here: <tag>text</tag>.

This is some pretty weird indenting, but it's easier for you to see what's going on in this example.

I'm using this way when there is not any row in the table, as well as, each row is quite complicated.

style.css:

...
#templateRow {
  display:none;
}
...

xxx.html

...
<tr id="templateRow"> ... </tr>
...

$("#templateRow").clone().removeAttr("id").appendTo( $("#templateRow").parent() );

...

if you have another variable you can access in <td> tag like that try.

This way I hope it would be helpful

var table = $('#yourTableId');
var text  = 'My Data in td';
var image = 'your/image.jpg'; 
var tr = (
  '<tr>' +
    '<td>'+ text +'</td>'+
    '<td>'+ text +'</td>'+
    '<td>'+
      '<img src="' + image + '" alt="yourImage">'+
    '</td>'+
  '</tr>'
);

$('#yourTableId').append(tr);

In my opinion the fastest and clear way is

//Try to get tbody first with jquery children. works faster!
var tbody = $('#myTable').children('tbody');

//Then if no tbody just select your table 
var table = tbody.length ? tbody : $('#myTable');

//Add row
table.append('<tr><td>hello></td></tr>');

here is demo Fiddle

Also I can recommend a small function to make more html changes

//Compose template string
String.prototype.compose = (function (){
var re = /\{{(.+?)\}}/g;
return function (o){
        return this.replace(re, function (_, k){
            return typeof o[k] != 'undefined' ? o[k] : '';
        });
    }
}());

If you use my string composer you can do this like

var tbody = $('#myTable').children('tbody');
var table = tbody.length ? tbody : $('#myTable');
var row = '<tr>'+
    '<td>{{id}}</td>'+
    '<td>{{name}}</td>'+
    '<td>{{phone}}</td>'+
'</tr>';


//Add row
table.append(row.compose({
    'id': 3,
    'name': 'Lee',
    'phone': '123 456 789'
}));

Here is demo Fiddle

I found this AddRow plugin quite useful for managing table rows. Though, Luke's solution would be the best fit if you just need to add a new row.

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

will add a new row to the first TBODY of the table, without depending of any THEAD or TFOOT present. (I didn't find information from which version of jQuery .append() this behavior is present.)

You may try it in these examples:

<table class="t"> <!-- table with THEAD, TBODY and TFOOT -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
<tbody>
  <tr><td>1</td><td>2</td></tr>
</tbody>
<tfoot>
  <tr><th>f1</th><th>f2</th></tr>
</tfoot>
</table><br>

<table class="t"> <!-- table with two TBODYs -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
<tbody>
  <tr><td>1</td><td>2</td></tr>
</tbody>
<tbody>
  <tr><td>3</td><td>4</td></tr>
</tbody>
<tfoot>
  <tr><th>f1</th><th>f2</th></tr>
</tfoot>
</table><br>

<table class="t">  <!-- table without TBODY -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
</table><br>

<table class="t">  <!-- table with TR not in TBODY  -->
  <tr><td>1</td><td>2</td></tr>
</table>
<br>
<table class="t">
</table>

<script>
$('.t').append('<tr><td>a</td><td>a</td></tr>');
</script>

In which example a b row is inserted after 1 2, not after 3 4 in second example. If the table were empty, jQuery creates TBODY for a new row.

TIP: Inserting rows in html table via innerHTML or .html() is not valid in some browsers (similar IE9), and using .append("<tr></tr>") is not good suggestion in any browser. best and fastest way is using the pure javascript codes.

for combine this way with jQuery, only add new plugin similar this to jQuery:

$.fn.addRow=function(index/*-1: add to end  or  any desired index*/, cellsCount/*optional*/){
    if(this[0].tagName.toLowerCase()!="table") return null;
    var i=0, c, r = this[0].insertRow((index<0||index>this[0].rows.length)?this[0].rows.length:index);
    for(;i<cellsCount||0;i++) c = r.insertCell(); //you can use c for set its content or etc
    return $(r);
};

And now use it in whole the project similar this:

var addedRow = $("#myTable").addRow(-1/*add to end*/, 2);

This is my solution

$('#myTable').append('<tr><td>'+data+'</td><td>'+other data+'</td>...</tr>');

In a simple way:

$('#yourTableId').append('<tr><td>your data1</td><td>your data2</td><td>your data3</td></tr>');

If you are using Datatable JQuery plugin you can try.

oTable = $('#tblStateFeesSetup').dataTable({
            "bScrollCollapse": true,
            "bJQueryUI": true,
            ...
            ...
            //Custom Initializations.
            });

//Data Row Template of the table.
var dataRowTemplate = {};
dataRowTemplate.InvoiceID = '';
dataRowTemplate.InvoiceDate = '';
dataRowTemplate.IsOverRide = false;
dataRowTemplate.AmountOfInvoice = '';
dataRowTemplate.DateReceived = '';
dataRowTemplate.AmountReceived = '';
dataRowTemplate.CheckNumber = '';

//Add dataRow to the table.
oTable.fnAddData(dataRowTemplate);

Neil's answer is by far the best one. However things get messy really fast. My suggestion would be to use variables to store elements and append them to the DOM hierarchy.

HTML

<table id="tableID">
    <tbody>
    </tbody>
</table>

JAVASCRIPT

// Reference to the table body
var body = $("#tableID").find('tbody');

// Create a new row element
var row = $('<tr>');

// Create a new column element
var column = $('<td>');

// Create a new image element
var image = $('<img>');
image.attr('src', 'img.png');
image.text('Image cell');

// Append the image to the column element
column.append(image);
// Append the column to the row element
row.append(column);
// Append the row to the table body
body.append(row);
