HTML Guide for 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>.
