How to add a colspan
in a header in gridview??
Normally a header looks like this...
<table class="table">
<thead>
<tr>
<th>Header1</th>
<th>Header2</th>
<th>Header3</th>
<th>Header4</th>
<th>HeaderA1</th>
<th>HeaderA2</th>
<th>HeaderA3</th>
<th>HeaderB1</th>
<th>HeaderB2</th>
<th>HeaderB3</th>
</tr>
</thead>
<tbody>
<tr>
<td>body1</td>
<td>body2</td>
<td>body3</td>
<td>body4</td>
<td>body5</td>
<td>body6</td>
<td>body7</td>
<td>body8</td>
<td>body9</td>
<td>body10</td>
</tr>
</tbody>
</table>
I want to make it look like this...
<table class="table">
<thead>
<tr>
<th rowspan=2>Header1</th>
<th rowspan=2>Header2</th>
<th rowspan=2>Header3</th>
<th rowspan=2>Header4</th>
<th colspan=3>Header A</th>
<th colspan=3>Header B</th>
</tr>
<tr>
<th>A1</th>
<th>A2</th>
<th>A3</th>
<th>B1</th>
<th>B2</th>
<th>B3</th>
</tr>
</thead>
<tbody>
<tr>
<td>body1</td>
<td>body2</td>
<td>body3</td>
<td>body4</td>
<td>body5</td>
<td>body6</td>
<td>body7</td>
<td>body8</td>
<td>body9</td>
<td>body10</td>
</tr>
</tbody>
</table>
To add a colspan
in a table's header you should insert attribute colspan
to headerOptions
of the column:
'headerOptions' => [
'colspan' => '2',
]
For the next column you should hide it's header with:
'headerOptions' => [
'style' => 'display: none;',
]
