When you pan with the mouse button/wheel held down, the panning stops when the cursor reaches the monitor edges. This forces user to release mouse, move it all the way back and re-grab it.
In some other editors you can continue to move the pointer and it will 'wrap' around your monitor, going from the opposite side of it, until released.

Basically you can pan until you reach the end of your table.

This mode will help those who have to work at scale and pan without unzooming. Please, add it!
