I'd like to render a bunch of table data in a TVML app similar to what iTunes music is already doing:
I looked through the templates in the TVML documentation site and didn't see anything that seemed relevant for rendering table data. Thoughts on how to do this?

You should be able to use the compilationTemplate and work on styling to achieve the style you want.
Also, if you have not downloaded the TVMLGuideCoreConcept or TVMLCatalog demo apps from Apple, must check it out. There are a lot of samples there that can help you.
