Re: Changing color of individual cells in a table

[Nickolai Dobrynin <dobrynin cs uwm edu>]

OK, let me simplify and rephrase my question.  Say I would like to have a
2x2 table with each cell colored differently and containing a short string
of text.  Anybody could explain how to achieve this behavior?

What would be the appropriate ModelColumns class to use and what would be
the appropriate TreeModel/TreeView structure?

I think, I don't really get the conceptual side of this.  Things should
become much simpler once I do.  I hope someone will help me with this, as I
don't have anybody else to ask.


Thanks much,

Nickolai Dobrynin
