HTML <td> colspan Attribute

The colspan attribute on a <td> tag specifies the number of columns a table cell should span, i.e., extend.

Example

#

A colspan attribute on a <td> element.
The last row spans, i.e. extends, two columns.

Investor Amount
Joel Nais $250
Tom Simpson $300
Greta Waltz $100
Total amount invested: $650
<style>
  table.tb {width:300px;border-collapse:collapse;}
  .tb th {background-color:lightblue;}
  .tb th, .tb td {border:solid 1px #777;padding:5px;}
</style>

<table class="tb">
   <tr> 
      <th>Investor</th>
      <th>Amount</th>
   </tr>
   <tr> 
      <td>Joel Nais</td>
      <td>$250</td>
   </tr>
   <tr> 
      <td>Tom Simpson</td>
      <td>$300</td>
   </tr>
   <tr> 
      <td>Greta Waltz</td>
      <td>$100</td>
   </tr>
   <tr> 
      <td colspan="2">Total amount invested: <b>$650</b></td>
   </tr>
</table>

Using colspan

The colspan attribute specifies the number of columns the table cell should span, i.e., extend.

A colspan value of "0" will span until the last column in the current <colgroup> (column group).

If no colgroup is defined it falls back to colspan="1", which is the same as no colspan at all.


Syntax

<td colspan="number">
