Yes that part is OK. I do have problem to add total weight and package at
bottom of the table like this:

Product_one   40kg
Product_two   60kg
-------------------------
Total:             100kg
===============

Because sometimes it is only a few products and other times many products.
I then need to summing them at bottom. One timer only 3 rows, other times
20 rows. The program need a way to add every singel product and see if it's
a few or many,
