I have a requirement at work that will require a grid with nested columns, similar to <td colspan="2"> in a normal table as shown below (forgive the pathetic ascii art):


**********************************
* Column *
**********************************
* Nested * Nested *
**********************************
* Nested * Nested *
**********************************
* Nested * Nested *
**********************************


A couple of questions: Is this even possible with thick Table implementations like JTable? More importantly is it possible with the yui-ext grid? Finally if it is not possible, but feasible with a bit of work I could use some prodding in the right direction. I've been doing OO javascript for a few years so I'm sure I could pull it off...

If the control does not support this and it would be very difficult to add, does nesting grids within grids make sense or is that just a path I don't want to go down.

Hope the question makes sense, and thanks in advance!
