A simple leg brace for a table with simple IKEA legs or those cheaper Amazon legs. I can create some other sizes if people would like, or feel free to adapt it and share.

The one shown in the pictures has been used for about 2 weeks, I've done it on 3 of the 4 legs on my table and it works very well. You can get away with pretty low density on the print, but if you're absoluting going ham on your table for whatever reason then bash that number up. I've attached a simple print profile but i'd recommend tinkering with it(Maybe lowering infill density) and adjusting supports.
