How to allow horizontal scroll of tables

I have a couple of tables that are more than 20 columns wide. The result is some ugly clustering of columns on the screen on the back end. With PHPMyAdmin, I can horizontally scroll and easily view all the data etc but I haven’t yet located an option to allow this in WP Data Access.

In the case of the Data Publisher, I can change the option from Responsive to Flat and the layout then becomes better ordered but still I can’t scroll beyond the viewable area of the WP screen.

I’m not sure if this is a limitation of WP Data Access or if WordPress disables horizontal scrolling.
