My data is such that I want to display values for the Employee and the Supervisor for a particular record. Instead of describing it, I'll show you a rough example:

```
<table><tr>
<th colspan="3">Employee</th>
<th colspan="3">Supervisor</th>
</tr><tr>
<th>Name</th>
<th>Last Activity</th>
<th>Count</th>
<th>Name</th>
<th>Last Activity</th>
<th>Count</th>
</tr>
</table>

```

How can I create this for a GridView? I essentially want 2 rows for the headings, and some of the cells should span more than one column.
