MadModifier - Latinrascalrg1's approach might be the easiest if the table is out consistently in all positions. I would allow use, further testing, and make some of the setups easier.
A very interesting problem. Based on the geometry of the machine, it looks like either or both of the up/down or cross ways could be worn enough to allow some "sag". I am assuming the table is lower as it gets further out (ram extended position). I would also take a close look at tracing the same path on the surface when the table is to the left and right positions. That should reveal whether the cross slide is worn, likely in the middle.
Figuring which surfaces are worn will be require a lot of work and disassembly.
What I am suggesting is map the table top in at least three positions - left right and center. You should map at least 9 positions on the table in each position. With enough math and data points you can isolate the flatness of the table with how the cross slide moves it. In a similar fashion, testing it at a few vertical positions would show how straight / flat the vertical movement is. Testing / indicating the sides of the table have not been considered in this suggestion.
Someone who knows better than me should weight in.
Best of luck.
