The question is asked for TH tags, but I couldn't find one for TD tags.
Can I put headings inside <td>
tags?
thead
is not h3
, if you use h3
inside td
element, it is absolutely fine, but if you use h3
as a direct child to tr
is invalid.
Inorder to use thead
you can use it like this
<table>
<thead>
<tr>
<th>This is table head and not h3</th>
</tr>
</thead>
<tfoot>
<tr>
<td>Foot Cell</td>
</tr>
</tfoot>
<tbody>
<tr>
<td>
<h3>It's completely valid to put your h3 here</h3>
Table cell
<p>You can also use p tag here
</td>
</tr>
</tbody>
</table>
But if you do it something like this, is invalid
<table>
<tr>
<h3>It's invalid</h3>
<td>This is a cell</td>
</tr>
</table>
You can always check here whether your markup is valid or not.
