I found this table on the curb a while back, less the leg hardware. No a relative could use it, and I’m wondering how to fix it up.
Cut a couple 2x4 sections to fill the truncated-triangular area and screw through them into all surfaces?
The legs have a hollow center drilled out, at the top, so I assume some metal piece with threaded holes fit there, and a metal plate anchored that to the skirt (?).
Another view:



Looks like a standard bracket, it even has the slots ready to go!

This is the best answer. If you are going to go with @dohpaz42@lemmy.world approach, just make sure to use a paddle bit to hog out the inset and use a washer so you can crank the bolts all the way.
Is it hot in here?
YEAH BROTHER, HOG CRANKING.
AWOOOOOOOOO!
