What if the table contains data that spans multiple columns?

For example, a personal calendar could have events that span across multiple hours, or even multiple days.

Data can span columns using the colspan attribute. The attributes accepts an integer (greater than or equal to 1) to denote the number of columns it spans across.

<table>
  <tr>
    <th>Monday</th>
    <th>Tuesday</th>
    <th>Wednesday</th>
  </tr>
  <tr>
    <td colspan="2">Out of Town</td>
    <td>Back in Town</td>
  </tr>
</table>

In the example above, the data Out of Town spans the Monday and Tuesday table headings using the value 2 (two columns). The data Back in Town appear only under the Wednesday heading.
