I think that all of the right questions have been asked, but I'm still not clear from your questions what you mean for sure about not being able to get the table in line. As James said the infeed table top top needs to be parallel with out feed table but not on the same level as the difference in height dictates the depth of cut. However, if you are referring to alignment in regard to both of the table being square with the fence, well, that's another matter. I had a PC table jointer that was not set up as far as the tables both being square with fence, I had to take the in feed table off and shim it into square.
Can you elaborate a little more on what you are referring to as far your problem is concerned.
What James said about the out feed table being common with the top of the blades is the secret of not getting any snipe. I you do get some snipe, you need to adjust the height of the out feed table. This is a very critical adjustment, but well worth the time it takes to tweak it into position and once st you should not have to mess with it again unless to check it when you change blades.
