Table Style Customization

On this setting tab, I see displays of my table at Desktop, Tablet and Mobile that reduce in width as the screen size reduces.

Is there something else I need to do in order to have this format display on the front end?

What I am seeing is that on narrower screens is that a horizontal scroll bar shows up instead which allows you to scroll off-screen to the right to see the other columns rather than the tables getting narrower to fit the screen.
