How do you level a snooker table cloth?

The floor is first leveled, if necessary. As the table is assembled, a long and a short level are used for the important surfaces. When the slate is laid on the table, the levels are again used as the slate is fastened, with very small shims used to level the slate. After the slate is fully tightened and finished, the level is checked. The level of effort required to level the table surface depends upon the quality of the table and proper assembly.
