A table system including at least one primary module and at least two secondary modules. The primary module includes a tabletop plate and a plurality of crossbars disposed parallel to each other and secured to the underside of the tabletop plate. A secondary module comprises a table leg having an upper end and a plurality of interlocking and bracing mechanisms disposed at the upper end of the table leg. A primary module and a secondary module together have an attached state and an interconnected state. The interlocking and bracing mechanisms have an open state and a closed state. In the attached state, each interlocking and bracing mechanism is in the open state, and is achieved by vertically setting the primary module onto the secondary module. In the interconnected state, each interlocking and bracing mechanism is in the closed state, interlocked independently into the interior portion of a crossbar.
