Creating a sortable tree/grid in Javascript

Question

I'd like to create a tree structure from JSON, but with multiple columns that can be sorted. I've seen lots of implementations of trees and grids but never one mixed.

Does anyone know of a plugin or feature for any Javascript toolkit that can make this happen so I don't have to re-invent the wheel here?

Answer 1

This seems pretty nice: http://www.max-bazhenov.com/dev/ux.maximgb.treegrid/index.html

Uses ExtJS, which has some licensing limitations you have to consider.

Answer 2

Here is an "official" example as well (top grid on the page), using the RowExpander UX.
