An improved elevating table apparatus provides a plurality of at least three telescoping legs that support a table top having an underside and an upper surface that provides a work surface upon which can be placed computers, office equipment and the like. A gear cluster is provided at the top of each leg that includes a plurality of gears, preferably bevel gears, that are engaged during use. Each leg has a hollow interior that holds a generally vertically extending, externally threaded rod, the rod having an upper end portion with a gear that forms a part of the gear cluster and a lower end portion that threadably engages a section of the leg. A single crank provides a drive shaft with a gear that forms a part of one of the gear clusters. A plurality of connecting linkages or connecting rods are provided that connect a center of the gear clusters to each of a pair of side gear clusters. When the single crank is rotated, all of the gear clusters and connecting rods or linkages rotate, each connecting rod or linkage having a gear at a connecting rod or linkage end portion that forms a part of a gear cluster. In this fashion, the crank can be rotated in one rotational direction that extends the length of each of the legs and elevates the table top. When the crank is rotated in an opposite rotational direction, all of the legs shorten in length so that the table top is lowered.
