Th only information that can be displayed about a product in the cart is what is listed in the template tag
[-- SC_Cart delete quantity image name sku price total --]
So those are (a delete or update button which isn't really part of the product) Name, SKU, graphic, each price, and total price. In addition if ordering options (pull down menus) and the Customer Text entry field are enabled they will also be displayed along with their associated text descriptions (header).
There is currently no way to add any additional product fields to the shopping cart table.
It may be possible to add some additional information using some of those field by custom coding the form that submits items to the cart. The ordering options in the form are called finopt as in <select name="138:finopt:0" size=1 > The text box is called freeopt and can be used to add some text to the product Customer Text entry field box.
There are examples in other forum posts that show how that can be done. Just search for freeopt or finopt and they should be listed.
