problem with Ext JS grid

iam new to Ext js iam displaying a tree inside a grid. it works fine.but according to my new requirement, i have to use seperate coloumn headers for parent no开发者_如何学Pythonde and child nodes.is it possible to have more than one coloumn header for a single grid?

ExtJs does not support multiple column headers out of the box. It would most likely be some type of plug-in but a quick google search didn't turn anything up.

There are two plug-ins you might find useful, the second one may be a sort of compromise.
