I didn't get a picture of how I secured the rails to the table but I drilled about 2" down into the rails, slathered on some Titebond glue and used 3" deck screws to screw the rails to the table. Here, I've got the table clamped in to place to check height and to get the cleat at the bottom of the knee braces figured out.
