I would map the table. An easy way would be to determine the high
and low spots.

Also, the main frame may be tweaked to shape the table itself. Think
about how they level pool tables.

since you would preferr to one Tee slot this table, you could drill
and tap strips of aluminum and both them from under neith and make a
flat surface of those parts and gain Tee slots in the process.
