When u jump, damage on table?

Ok, I see some white spot and perhaps a tiny dump in table(very small, you can allmost not feel it, but it is there)

The white spots are what most call burn marks. You can reduce this by making sure your cloth and balls are pristine.

Chalk is abrasive and dirty balls can be too. At the very least dirty balls add friction and friction causes heat and possible damage to the cloth.

Just keep things clean and all will be well. You'll also enjoy the game more.

Take a very damp cloth over the spots and most if not all will disappear.
