Can we merge columns in gridpanel

Hi..

In gridpanel can we merge two columns in grid panel.
Ex: i have startdate and enddate columns.
they are displaying in gridpanel.
now i want display those two columns in single column as 'DataLimit(startdate+enddata)'

please send any examples.

thanks ,
satya

Code:

<ext:Column ColumnID="Employee" Header="Full Name" DataIndex="LastName" Sortable="true"> 
<Renderer Handler="return ''+record.data['LastName']+','+record.data['FirstName']" />               
</ext:Column>

Why don't you try lower levels like database level or object level?

In my opinion this will be much faster and easier...
