Hello 
Unfortunately, the “Microsoft Word Templates” modules do not support formatting of any kind.
They support only plain text with no HTML characters/items.
As far as I know, they do not use Microsoft API but a different tool.
It then might be better to use "***Google Docs***" modules where you can create new documents (tables) using HTML code (which should support such formatting).
You could then export the Google documents from Google Drive using the built-in "convert" feature below.
This topic might also help create dynamic HTML tables for document creation.
I hope it helps.
