It is imperative that the building table is flat with no twist or humps in it. My table is a welded truss frame that will not twist. Any spacers that are used to hold clecoed wings or other parts should also be parallel and true. How flat and true (within 1/32 over 12 feet, if you want the plane to fly straight)?

Not me, but it has to be 2-300 times!!! Gary Boothe Cool, CA 601 HDSTD, WW Conversion Tail done, working on wings.

On the other hand, I don't think it is necessary to have something as big as a wing within 1/32 inch of perfect. This is only one of many things that can impact a plane's natural ability to fly straight and true. Some of the other things include: Rigging of both structure and control surfaces; presence or absence of a passenger; exact fuel situation; power setting; weight and balance impact of baggage and cargo; and general weight and balance of the structure. In the end it is elevator and aileron/rudder trim that will make the plane fly straight. I think it is a great idea to build as true a structure as you can, but I wouldn't lose sleep over how close to perfect it comes out.
