web page content regex based security

I am wondering if the following is technically doable or not, but I am gonna give it a shot anyway. Is it possible to limit the user access on a specific web page and that access is based on a specific regex? I have the following scenario: the web page is just a compilation of tones of tables (like excel tables) and I would like to limit a specific user access to their table (access = view). E.g: user "A" has access to the table "TABLE-A" only and cannot scroll down or up to see the other tables.

thinking about digging into reverse proxy and stuff ...
