column reorder or exchange in ReorderingTreeGridExample

[shivrajvjadhav]

Hi,

I was checking demo for http://www.sencha.com/examples/#Exam...deringtreegrid
ReorderingTreeGrid

I could be able to reorder rows in grid, but if I try to reorder/exchange column, it doesn't work.
e.g. column order is Name, Auther, Genre. If I try to move Genre to second position, so I can see Name, Genre, Author. It didn't allow me.

Is there any property which I need to enable in oder to exchange/reorder columns?

How to do it in the same java code:
ReorderingTreeGridExample
???

Can someone reply how to reorder columns in TreeGrid example demo?
I tried doing it, but i could be able to reorder only rows and not columns.Is it supported in TreeGrid?
