Hey, back again.. I don't suppose there's a way to modify the full shopping cart is there?

function uc_cart_view_table($op, &$form)
from cart.module looks good but its not a theme_ function :\

I need to add a taxonomy->tid and field from each product in the cart. I could do with tweaking the layout abit too. One thing thats always frustrated me is the table row containing 'SubTotal'. It has no class or anything to latch onto in order to style it differently from the product rows above it.

Thanks for reading,
Marc
