Currently, we have a fixed table width of 1800px on confluence end.
Given this, if we make a page as full width it looks good on the small screen of a 16 inch laptop or 24 inch screen however it's not beneficial for larger screens of upto 50 inches and the page does go to full width.

Customers wuld like to have the ability of having a flexible table width on a page as the screen size varies.
