Mine is similar dimensions to Paul's in post number two above. As my shop is very limited in size, I made three tables 6 ft by 4 ft that attach end to end by screwing 2x4s onto the side for alignment. Half inch lag screws in the bottoms of the legs for height adjustments. Framing all glued and screwed with gussets. All painted white, three quarter inch plywood top. Sturdy shelf underneath.
Right now, two sections are together and one is off to the side.
