Current behavior
In the web demo, in the first table if you try to drag the rightmost border, the blue line in the picture below shows up and the last column didn't get resized. Also, the page is not responding after this.

Expected behavior
I am expecting either 1 or 2 below:

1. Dragging is disabled on the rightmost border.
   or 2. Dragging is enabled on the rightmost border. The last column gets resized, which means the entire table gets resized.
