How to highlight the cell of a Jtable and keep it highlighted

Question

I Have a Jtable with data inserted and I want to highlight each cell one by one and keep it highlighted until I select each cell one by one again to un-highlight each of them.

I have an attached code where I'm able to highlight each cell but when I move to another cell, the previous cell is un-highlighted.
