Remarks

Valid tags within the THEAD element include:

You can specify only one tHead object specified for any given table object.

The table object and its associated elements have a separate table object model, which uses different methods than the general object model. For more information about the table object model, see Building Tables Dynamically.

Examples

The following code example uses the THEAD element and the TABLE, TBODY, TD, and TR elements to create a table that includes the first row in the table header and the second row in the table body.


<table>
<thead>
  <tr>
    <td>This text is in the table header.</td>
  </tr>
</thead>
<tbody>
  <tr>
    <td>This text is in the table body.</td>
  </tr>
</tbody>
</table>
