Hello,
UPDATE: Tables without spacing between them
That's an MS Word limitation. MS Word requires adding at least one paragraph between tables. If you open MS Word, you can try it: after adding a table to a document, and then you try to add another table, MS Word doesn't allow it unless you add at least a paragraph.
You can get the minimum space between tables by adding a paragraph between them and setting the spacing and font-size to the minimum value:

You can change spacing and font-size values with phpdocx.
Using removeWordContent from DOCXPath you can force the removal of those paragraphs between tables that MS Word requires, but please note that then MS Word may display a corrupted document error when trying to open it.
Regards.
