[flexcoders] Customizing header's datagrid to merge cols

[wazzameleon]

Hie,

I'm trying to custom the header of a datagrid to merge header's column
to have something like that :

-----------------------------------------------------
|           | column 2 and 3 merged     |           |
| column 1  |---------------------------| column 4  |
|           | column 2     | column 3   |           |
-----------------------------------------------------
|           |              |            |           |
|           |              |            |           |
|           |              |            |           |


Does someone has already done that ?

Thanks
