Does anyone (Alex included) have code or instruction on creating a file data grid like the one created here?

Thanks Alex. It took me a while to really understand the code, but I got it working. Great tool by the way. It has really helped me to learn more about javascript. It's also given me a context for interfacing php/js/html, great skills to be learning. I don't mind all the toil.
