IRWIN VISE-GRIP Original Locking C-Clamp, 11", 19

Get clamps like this first https://www.amazon.com/VISE-GRIP-Original-Locking-C-Clamp-19/dp/B00004SBBH C clamps and F clamps too. That's good enough Later if you want to add some holes grab one of these https://www.amazon.com/VEVOR-Magnetic-Diameter-Electric-Improvement/dp/B0DZBS8M1K but the table should be at least 1/4" thick for that, but you can get by fine without dog holes and fixture clamps.
