I am glad to help but I now feel that I have some responsibility to
protect you from the terrors of the JTable control. First, you should
read <http://java.sun.com/products/jfc/tsc/articles/architecture/>.
Don't worry if you don't understand it all. Next, go ahead with
whatever you are trying to do with the JTable control. If you are
having trouble with your code go back and read the article again. The
separation between the "model" and the "view" is a powerful concept
but it makes the transition from another environment that hides that
distinction a significant step.
