[flexcoders] AdvancedDataGrid: Columnspan in a single row?

[Dorian Roy]

Hi,

Is there a way to have an ItemRenderer span two or more columns inside  
an AdvancedDataGrid only in one specific row?

Basically I need something like this:

1    |  2    |  3    |   4   |
span 3 cols    |   4   |
1    |  2    |  3    |   4   |

Thanks
Dorian
