I just went to the IKEA a couple of weeks ago and found 2 lack tables in the scratch and dent section for $10 each. I had a dickens of a time trying to remove the plugs in the bottom of each leg so I just ended up sawing the bottom 3 inches from one of the table’s legs. This was done in order to shove and screw a 1 & 3/4" square dowel in each leg to hold the rack rails in place. Works so far and is cheap.
