One of the requests we get over on the display tag project is a way to have static headers. Basically, this means that a user could scroll down through all the records on a page and the header would stay in place. The next generation of the tag library has a <thead> and <tbody> that makes this fairly easy to do. For instance, just by adding
style="height: 400px; overflow: auto" to the <tbody> tag - you get the desired effect. Cool stuff - only seems to work in Mozilla though. Any IE/CSS experts out there that can explain why it doesn't work in IE?
