[ext js] Renderer for ColumnTree?

Question

Hello!

I'm trying to add a custom renderer to a ColumnTree in Ext JS. Since it appears(?) that this isn't supported, does anyone know of any workaround to use a renderer? Here's a snippet of code - let's just say (hypothetically) that I have a renderer I'd like to use for the documentsVersion tab below - does anyone have any ideas?

return new Ext.tree.ColumnTree({
    autoHeight: false,
    rootVisible: showRoot,
    autoScroll: false,
    id: (!treeId)? window.mainTreeId: treeId,
    loader: (!loader)?window.docTreeLoader:loader,
    columns: [{
         header:"${documentsTitle}",
         width: windowWidth * 0.40
     },
     {
         header:"${documentsVersion}",
         width: windowWidth * 0.10,
         dataIndex:'version'
     },

Thanks!

As I can see from this ExtJS forum post they still evaluate renderer column property in their ColumnNodeUI.js subclass for rendering column data.

So you may try to add renderer property along with header, width and dataIndex.
