[flexcoders] AdvancedDataGrid: Columnspan in a single row?

[arkona3000]

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    |
I span 2 cols|  3    |
1    |  2    |  3    |

Thanks
Dorian
