rowspan Attribute

Where to use the rowspan Attribute

• As Type Number - default="1":
  rowspan is declared on the elements: th, td

Description

The rowspan attribute is used on a table cell (td or th) to specify the number of rows to be spanned by the cell.

<table border="1"><tbody>
<tr><td rowspan="3">This cell spans three table rows</td> <td>but</td></tr>
<tr><td>each</td></tr>
<tr><td>other cell</td></tr>
<tr><td>spans</td> <td>only one</td></tr>
</tbody></table>

The default value is "1" and the special value of "0" indicates that the cell should span all remaining rows, from the current row to the last row in the current table section (either thead, tbody or tfoot). If none these three table section elements are present, the cell should span to the last row of the table itself.

Note: the special case of rowspan="0" is not very well supported across user agents.

Although not stated officially (not that I can find, anyway) any cell which spans multiple rows should not cross a boundary between thead, tfoot or tbody elements.
