Hide Tables, but keep view as "all records"

Yes, it is good practice, to hide tables where the users have no business really looking at the table in isolation. The typical use case for this is One Order has Many Lines and really the user would always be looking at Orders with an embedded table of Order Line opposed to a giant table full of random order lines from all the orders.  

So "np", just go to those regular non admin Roles and look for the User Interface Tab.  You will be able to use a checkbox to Hide In Table Bar.
