My demo is at: http://www.sperling.com/freeware.php So, I have an idea of what's involved. If this just for display, then it shouldn't be too difficult to display the end results in a table -- provided, you know in advance the largest any row will be. It will be a simple grid, unless you want to play with column spacing, which will be very difficult indeed to manage. As for cells not being individually sized, you're right they can't be sized, but they do automatically size to their contents and that can be varied as well shown with different background colors. Are you going to use this for something other than display, is it functional in some way? Because if you're going to add functionality, such as editing, deleting, sorting, then you have a big chore in front of you. As for using recursive functions, absolutely -- they make the process (and code) much less. However, you need to wrap your mind around things spinning around to their conclusion, which is sometimes difficult to imagine.
