I have two tables for building. One is 31" wide x 39" tall x 77" long. The 31" side is against the wall so I have access to 3 sides while standing. I made it 39" tall because I don't like to bend over and I am 6' 1" tall. This bench has removeable pylons on each end with a 7/8" dia.hole 8" above the bench top surface. I have a 1" square aluminum tube that is the same length as the bench. The tube can rotate 360 degrees and I mount bulkheads on the tube or templates for hot wire foam cutting. I have adjustable length metal feet in the bottom of the legs 6 places that I adjust to keep the table dead flat.

The other table is 29" deep x 30" tall x 96" long. On top of it I have a top out of MDF that is hinged in the middle length wise for setting wing dihedrals. The MDF top is 2" above the plywood top at the hinge line and has height adusting screws approx ever 12" so I can adjust the MDF for flatness no matter what dihedral angle is used. The tables are cover with work today so no pictures right now.
