I picked up the plans for this table from Bill Vondane's site.  It's a pretty good plan and simple to put together.

 

Bill of materials for one 3' x 8' work table

1 3/4" x 4' x 8' particle board - ripped to 3' x 8' sheet
1 1/2" x 4' x 8' particle board - ripped to 3' x 90" sheet
10 2" x 4" x 8' Premium Studs
#8 x 2 1/2" Wood Screws
Carpenter's Wood Glue
You will be building the table upside down from the top down.  make the top frame first, it will be small enough to allow the table top to overhang the frame by 1 1/2" all the way around.  The lip is good for clamping things to it.  Then put the particle board top on.  Turn it over and attach the legs and shelf braces (leave the 8" bottom outer leg  pieces uncut until the end and cut them to fit), then turn it over and put the shelf in...

This is a picture of the finished table.  The table was shortened from the plans to

63" (5'3"), in order to fit in primer

booth.  The top is covered in

mesh screen so the parts will

stay in place when spraying.
