Add section with product descriptions before price table


i’m trying to create a template but i’m not being able to get the wanted results.

I create a PDF template for Quotes module, using the Quote Group Sample.
This creates correctly the table with the groups, products and pricing.

I want to create a section (table) before this, with only product name and product description.

However, when I create it, the whole template gets messed up.

Is this supported ?

Thanks for your help.
