How to add sum row in each page

[VladaMitic]

Hi, First thanks for the great package.
I am trying to render a multi-page table in word, and I really didn't have a problem with that. But I need to add the last row on each page that is the sum of certain columns on that page, accept the last page where that row is a sum of all certain columns. Is there any solution or recommendation for this?

docx don't have any support for this, so it seems you may have to write custom logic to calculate the columns etc
