What I'm looking for is a table for which I can specify very strict selection procedures. I want to be able to not only select rows and columns, but also select cells in a diago...
This is driving me absolutely insane. I know that, to change the formatting of table cells with JTable, I have to use my own renderer. But I cannot seem to implement this properly.
