Nice table, but take your time putting it together.  Assembly is easiest if you do it on a couple of sawhorses.  2 scratch awls and wood shims help aligning screw holes.  It's best to install screws on the middle boards and work your way out, and spacing will take care of itself.  A few screw holes may need to be drilled out with a 1/8th bit.  Let the glued end caps dry 24 hours before use.  Good luck.
