On to the question...
How you will do this depends on the reason you are doing it... If you override isCellEditable() in your table model the cell selection is less obvious, but you cannot edit the value in the cell. If you want there to be no cell selection at all, or if you need to edit cell values, then you need to make new CellEditors and set the background color to be the selection background color and remove the colored border.
