GCs low or high along long rails

[derangedhermit]

Two tables in a local room have opposite problems. On one table, slow shots, in either direction, parallel and close to each long rail drift toward that rail. On the other table, on one rail, slow balls drift off one of the long rails, but shots down the other long rail don't drift at all.

The center three+ feet of both tables seem flat - no drift shooting slow from head rail to foot.

I think one is a II and one is a III, both 9'. Is this kind of thing a common, fixable problem?

Unless you're looking at the level of the slates with a machinist level it's hard to tell.
