I have write this code which creates a Word file. All the document has only one table with four columns and 10 rows in each page. The problem is that the columns has not the right width to fill the page, and the rows has not the right height to fill the page.

Print screen:

As for the columns I found I manual solution.

but I don't know how to apply it in python-docx. (I am searching something like: https://reference.aspose.com/words/python-net/aspose.words.tables/autofitbehavior/)
