>The prefix "h" for element "h:dataTable" is not bound.

That's not a taglib problem, it's a basic XML problem. In XSLT, as in XML, you need to declare your namespace prefixes.

Unfortunately I think you're trying to tackle quite a tricky XSLT problem when you haven't learnt enough of the basics to tackle simple problems. I really would recommend reading some good books or tutorials and starting with easier problems. You can't expect to jump in a car and start driving without having some lessons first.
