Thank you. I was able to get it figured out by combining a couple of your samples. Basically I just want to gang all the cells together. It's really dumbing down a lot of the capabilities of TableMatrix, but I am working with spreadsheet data & I like the "cellular" look of TableMatrix.
This is my first production Tk project and I've worked with it enough now that it is starting to make sense to me. Give a monkey a typewriter and eventually he will write War and Peace.
