HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as tbody.
A table row tr has been found, containing no td cells. Check the table and remove empty rows.
Table contents is organized in rows using the <tr> element, which must contain cells using the <td> element, as in this example:
<table>
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>Liza</td>
<td>12</td>
</tr>
<tr>
<td>Jimmy</td>
<td>14</td>
</tr>
</tbody>
</table>
A tr with no td cells on it will raise an issue, as in this example:
<table>
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
</tr>
<tr>
<td>Jimmy</td>
<td>14</td>
</tr>
</tbody>
</table>
Note that self-closing <tr/> elements also count as empty rows as are like <tr></tr>.
