Adjusting Table size?s

I am trying to adjust many of my tables. I need to pull out to all most full screen to see many of them.

But when i adjust them it is like it has a invisible wall on the right side that moves in and blocks the view so if i make a table small so it fits right i can not shrink down the view as the white wall moves in over it all blocking it?

Here you can see the tables getting cut off by this white area that moves in from the right. It dose this on a pivat view as well
