Is your table a stand alone table with 4 screws going through the feet of the table (like a center post table with 4 toes)? Or is your table a dinette table on 2 metal pedestals that are held upright in a flat pancake type "thing" on the floor, the post insert, and then the table top sit on top of the posts. The table top is then used to convert the dinette into a bed?
If a stand alone table, the screws can be anchored back into the floor. Just move the table an inch any direction and you are good to go.
If it's the dinette table, you can pick up the floor inserts and simply rotate them and screw them to the floor. If your original was plastic, you can swap them out with aluminum.

If yours is a stand-alone table and the legs (feet) are now broken, you can replace with any kind of table that fits the space.
