I have four table headers:
$scope.headers = ["Header1", "Header2", "Header3", "Header4"];
And I want to be able to sort my table by clicking on the header.
So if my table looks like this
H1 | H2 | H3 | H4
A H D etc....
B G C
C F B
D E A
and I click on
H2
my table now looks like this:
H1 | H2 | H3 | H4
D E A etc....
C F B
B G C
A H D
That is, the content of each column never changes, but by clicking on the header I want to order the columns by, the rows will reorder themselves.
The content of my table is created by a database call done with Mojolicious and is returned to the browser with
$scope.results = angular.fromJson(data); // This works for me so far
The rest of the code I have cobbled together looks something like this:
<table class= "table table-striped table-hover">
<th ng-repeat= "header in headers">
<a> {{headers[$index]}} </a>
</th>
<tr ng-repeat "result in results">
<td> {{results.h1}} </td>
<td> {{results.h2}} </td>
<td> {{results.h3}} </td>
<td> {{results.h4}} </td>
</tr>
</table>
How do I order the columns from this point, just by clicking on the header at the top of the table?

I think this working CodePen example that I created will show you exactly how to do what you want.
The template:
<section ng-app="app" ng-controller="MainCtrl">
<span class="label">Ordered By: {{orderByField}}, Reverse Sort: {{reverseSort}}</span><br><br>
<table class="table table-bordered">
<thead>
<tr>
<th>
<a href="#" ng-click="orderByField='firstName'; reverseSort = !reverseSort">
First Name <span ng-show="orderByField == 'firstName'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
</a>
</th>
<th>
<a href="#" ng-click="orderByField='lastName'; reverseSort = !reverseSort">
Last Name <span ng-show="orderByField == 'lastName'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
</a>
</th>
<th>
<a href="#" ng-click="orderByField='age'; reverseSort = !reverseSort">
Age <span ng-show="orderByField == 'age'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
</a>
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="emp in data.employees|orderBy:orderByField:reverseSort">
<td>{{emp.firstName}}</td>
<td>{{emp.lastName}}</td>
<td>{{emp.age}}</td>
</tr>
</tbody>
</table>
</section>
The JavaScript code:
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope) {
$scope.orderByField = 'firstName';
$scope.reverseSort = false;
$scope.data = {
employees: [{
firstName: 'John',
lastName: 'Doe',
age: 30
},{
firstName: 'Frank',
lastName: 'Burns',
age: 54
},{
firstName: 'Sue',
lastName: 'Banter',
age: 21
}]
};
});
Another way to do this in AngularJS is to use a Grid.
The advantage with grids is that the row sorting behavior you are looking for is included by default.
The functionality is well encapsulated. You don't need to add ng-click attributes, or use scope variables to maintain state:
<body ng-controller="MyCtrl">
<div class="gridStyle" ng-grid="gridOptions"></div>
</body>
You just add the grid options to your controller:
$scope.gridOptions = {
data: 'myData.employees',
columnDefs: [{
field: 'firstName',
displayName: 'First Name'
}, {
field: 'lastName',
displayName: 'Last Name'
}, {
field: 'age',
displayName: 'Age'
}]
};

</html>Here is a fiddle that can help you to do this with AngularJS
http://jsfiddle.net/patxy/D2FsZ/
<th ng:repeat="(i,th) in head" ng:class="selectedCls(i)" ng:click="changeSorting(i)">
{{th}}
</th>
Then something like this for your data:
<tr ng:repeat="row in body.$orderBy(sort.column, sort.descending)">
<td>{{row.a}}</td>
<td>{{row.b}}</td>
<td>{{row.c}}</td>
</tr>
With such functions in your AngularJS controller:
scope.sort = {
column: 'b',
descending: false
};
scope.selectedCls = function(column) {
return column == scope.sort.column && 'sort-' + scope.sort.descending;
};
scope.changeSorting = function(column) {
var sort = scope.sort;
if (sort.column == column) {
sort.descending = !sort.descending;
} else {
sort.column = column;
sort.descending = false;
}
};
I had found the easiest way to solve this question. If efficient you can use

I'm just getting my feet wet with angular, but I found this great tutorial.
Here's a working plunk I put together with credit to Scott Allen and the above tutorial. Click search to display the sortable table.
For each column header you need to make it clickable - ng-click on a link will work. This will set the sortName of the column to sort.
<th>
<a href="#" ng-click="sortName='name'; sortReverse = !sortReverse">
<span ng-show="sortName == 'name' && sortReverse" class="glyphicon glyphicon-triangle-bottom"></span>
<span ng-show="sortName == 'name' && !sortReverse" class="glyphicon glyphicon-triangle-top"></span>
Name
</a>
</th>
Then, in the table body you can pipe in that sortName in the orderBy filter orderBy:sortName:sortReverse
<tr ng-repeat="repo in repos | orderBy:sortName:sortReverse | filter:searchRepos">
<td>{{repo.name}}</td>
<td class="tag tag-primary">{{repo.stargazers_count | number}}</td>
<td>{{repo.language}}</td>
</tr>
Here is an example that sorts by the header. This table is dynamic and changes with the JSON size.
I was able to build a dynamic table off of some other people's examples and documentation. http://jsfiddle.net/lastlink/v7pszemn/1/
<tr>
<th class="{{header}}" ng-repeat="(header, value) in items[0]" ng-click="changeSorting(header)">
{{header}}
<i ng-class="selectedCls2(header)"></i>
</tr>
<tbody>
<tr ng-repeat="row in pagedItems[currentPage] | orderBy:sort.sortingOrder:sort.reverse">
<td ng-repeat="cell in row">
{{cell}}
</td>
</tr>
Although the columns are out of order, on my .NET project they are in order.
Use a third-party JavaScript library. It will give you that and much more. A good example is datatables (if you are also using jQuery): https://datatables.net
Or just order your bound array in $scope.results when the header is clicked.
Try this:
First change your controller
yourModuleName.controller("yourControllerName", function ($scope) {
var list = [
{ H1:'A', H2:'B', H3:'C', H4:'d' },
{ H1:'E', H2:'B', H3:'F', H4:'G' },
{ H1:'C', H2:'H', H3:'L', H4:'M' },
{ H1:'I', H2:'B', H3:'E', H4:'A' }
];
$scope.list = list;
$scope.headers = ["Header1", "Header2", "Header3", "Header4"];
$scope.sortColumn = 'Header1';
$scope.reverseSort = false;
$scope.sortData = function (columnIndex) {
$scope.reverseSort = ($scope.sortColumn == $scope.headers[columnIndex]) ? !$scope.reverseSort : false;
$scope.sortColumn = $scope.headers[columnIndex];
}
});
then change code in html side like this
<th ng-repeat= "header in headers">
<a ng-click="sortData($index)"> {{headers[$index]}} </a>
</th>
<tr ng-repeat "result in results | orderBy : sortColumn : reverseSort">
<td> {{results.h1}} </td>
<td> {{results.h2}} </td>
<td> {{results.h3}} </td>
<td> {{results.h4}} </td>
</tr>
You can use this code without arrows.....i.e by clicking on header it automatically shows ascending and descending order of elements
