JTable about Selection Mode

Question

I need to implement a new selection mode similar to MULTIPLE_INTERVAL_SELECTION but every time the user clicks on the table the entire column must be selected (or deselected if the column was selected before) and the other columns must stayed selected as If control key was pressed without being pressed! Does anyone know how to figure this out?

Answer 1

I have figured it out in a different way... The problem is the way the screen is refreshed... do you know a way to solve this issue?
