hi here it is .,
http://codeguru.earthweb.com/java/articles/665.shtml
It has multiple radio buttons in a button group for a cell. I have used Cell
Renderer and Cell Editor for the table.
To make it simple I have it based on the one already in Codeguru.com that
explains how to use radio buttons as cell editor and renderer.

Subject: Radio button in JTable
Hello all, could please direct me to some code snippet and/or guide
which helps me putting radio buttons in a JTable. Tutorial from Sun is
not very elaborate on cell renderers.
Thanks in advance,
