As per my answer here, it is also possible to use a table head (which can be empty) and apply relative widths for each table head cell. The widths of all cells in the table body will conform to the width of their column head. Example:
HTML
<table>
<thead>
<tr>
<th width="5%"></th>
<th width="70%"></th>
<th width="15%"></th>
<th width="10%"></th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Some text...</td>
<td>May 2018</td>
<td>Edit</td>
</tr>
<tr>
<td>2</td>
<td>Another text...</td>
<td>April 2018</td>
<td>Edit</td>
</tr>
</tbody>
</table>
CSS
table {
width: 600px;
border-collapse: collapse;
}
td {
border: 1px solid #999999;
}
Alternatively, use colgroup
as suggested in Hyathin's answer.
