Have you used the User Defined Table Module?
I must say a few things about the User Defined Table (UDT) module for DotNetNuke, I have seen it, but hardly ever used it. I had a site that was using it that I needed to make some changes to tonight, I've been putting off the changes because I was afraid of them.
Wow, the UDT module rocks, if you haven't used it check it out, I will try to do a full writeup on the module soon, but long story short. You can create a lot of different formats with your data using the XSL, but even if you don't know or feel comfortable with XSL check out the XSL generator that is included in the module! It makes like way easier!
