this is version, table top connector round, uses round posts such as pvc tubing., i made caps and footing for the round posts, tubing should be s 1.25 inches in diameter. screws will be needed to secure the table to the post connectors. the connectors have a stop inside to stop the tubing from going all the way through. so there is no need for screws to connect the tubing to the connectors. so you put the tube section on the foot, then a connector to the tube, then the cap. and it can be heightened by continuing the tube connector process.via a connector for the outside with 1 table edge. and can be expanded sideways via a connector with 2 edges for two tables to go side by side.
