JTable with ImageIcons does not react to even handling

Question

Hi.
I have a populated JTable with ONLY ImageIcons in it. I need to generate event responses on mouseClicks. However, any event listener I associate with this, nothing seems to be happening.
(Somehow, I'm guess the ImageIcons - which are rendered on a JLabel, are/is the source of all troubles!!)
The code is below :

import java.awt.Point;
