Ubercart

That information is part of uc_product_cart_display(). This gets passed to uc_cart_view_table() and the hook_table_alter() you're planning on writing as an element of $form['items']. You can get the description (body) and unit price (sell_price) by using node_load() on the nid contained in the item.

Is that enough to get you started?

I begin to create a little module that make that in the cart view and the order view. I will post it tomorrow (because I'm not on my work PC now).

But it's true, it's should be good to implement that in core, it's very easy to do and this could be usefull for a lot of people

I just posted a contribution that add extra columns to some tables.

It add an unit price to cart as you want

The snippets people have been posting on this thread, and elsewhere, work great for the regular cart page.

But what about cart review table on the Checkout page? I'm still trying to get that going.

In exploration of this issue I'm simply trying to just affect that cart review table in SOME way but after going through 5 functions I still can't seem to be able to touch it. Like changing the title from "Cart Contents" to anything else. Am I missing something? I'm clear cache on the Performance page, and refreshing admin and/or module pages for the hell of it.
