html table cells combine

Question

I have a table with 3 rows and 3 columns. How can combine last row columns? My html:

<table>
  <tr><td></td><td></td><td></td></tr>
  <tr><td></td><td></td><td></td></tr>
  <tr><td>Here I need a cell by all width</td></tr>
</table>

Answer 1

Use the colspan attribute:

<tr><td colspan="3">Here I need a cell by all width</td></tr>

The colspan attribute defines the number of columns a cell should span.

There is a related attribute rowspan that achieves the same for rows.
