How to get list of users who updated a confluence page using confluence Tables

[Saikumar Potharajula]

Need to get the list of users who updated a page within space. 

Note: we have many spaces and page title may be duplicated across the spaces.

-->Had a thought of doing group by on page_title,spaceid and get the list of users. But space_id is null for all the page versions except current version. So I cant include space_id in group by.
--> If I do group by on page_title only, it will give wrong results as page title may be duplicated across spaces( ex: Overview page in every space).

Any other approaches please
