1. An elevating table apparatus comprising: a) a table top providing an upper work surface and a lower surface;b) a plurality of table legs, each leg including telescoping leg members, one telescoping leg member being a sleeve member that has a bore that is receptive of the other leg member;c) a geared mechanism on the upper end portion of each leg that enables a user to elevate the table top relative to an underlying support surface or floor, the geared mechanism including multiple gears that rotate together;d) each leg having a gear box housing that envelops the geared mechanism and that extends circumferentially around and radially away from the geared mechanism, wherein the housing is structurally connected to both the table top and each leg;e) the gear box housing being connected to the leg below the geared mechanism;f) the gear box housing having an upper peripheral edge portion that is structurally connected to the table top and that extends radially out from the geared mechanism, and wherein the gear box housing surrounds the geared mechanism; andg) wherein there are no connections below the gear box housing that span in a generally horizontal direction from one leg to another leg below said table top. 2. The elevating table apparatus of claim 1 wherein the geared mechanisms of the legs are manually movable using a crank. 3. The elevating table apparatus of claim 1 wherein at least one of the legs is supported by a lower foot that extends in front of and behind the leg. 4. The elevating table apparatus of claim 3 wherein the lower foot has a socket that is receptive of the lower end of a said leg. 5. The elevating table apparatus of claim 3 wherein each foot is rotatable upon a said leg so that feet on multiple legs can be oriented to form an acute angle. 6. The elevating table apparatus of claim 1 wherein one leg member is an inner member that moves up and down relative to the other leg member. 7. The elevating table apparatus of claim 6 wherein one leg member is an outer, stationary member. 8. The elevating table apparatus of claim 1 further comprising a caster fitted to the bottom of at least one of the legs. 9. The elevating table apparatus of claim 1 wherein the leg members are each generally cylindrically shaped. 10. An elevating table apparatus comprising: a) a table top providing an upper work surface and a lower surface;b) a plurality of table legs, each leg including telescoping leg members including an inner member and an outer sleeve member that has a bore that is receptive of the inner member, and wherein each leg has a minimum leg height and a maximum leg height;c) a geared mechanism on each leg that enables a user to elevate the table top relative to an underlying support surface or floor;d) a gear box housing that envelops that geared mechanism and that is structurally connected to both the table top and each leg;e) the gear box housing being connected to the leg with a connection that extends below the geared mechanism and extending upwardly to engage the table top;f) the gear box housing having an upper peripheral edge portion that is structurally connected to the table top and that extends radially out from the geared mechanism, and wherein the gear box housing surrounds the geared mechanism; andg) wherein there are no connections below the gear box housing that span in a generally horizontal direction from one leg to another leg below said table top. 11. The elevating table apparatus of claim 10 wherein the geared mechanism is movable using a crank. 12. The elevating table apparatus of claim 10 wherein at least one of the legs is supported by a lower foot that extends in front of and behind the leg. 13. The elevating table apparatus of claim 12 wherein each leg and foot are rotatable so that feet on multiple legs can be oriented to form an acute angle. 14. The elevating table apparatus of claim 10 wherein the inner member moves up and down relative to the outer sleeve member. 15. The elevating table apparatus of claim 10 further comprising a caster fitted to the bottom of at least one of the legs. 16. The elevating table apparatus of claim 10 wherein the lower foot has a socket that is receptive of the lower end of a said leg and the lower end of the outer sleeve member. 17. The elevating table apparatus of claim 10 wherein the inner member and outer sleeves are generally cylindrically shaped. 18. An elevating table apparatus comprising: a) a table top providing an upper work surface and a lower surface;b) a plurality of table legs, each leg including multiple leg members including an inner member and an outer member that has a bore that is receptive of the inner member;c) a geared mechanism on each leg that enables a user to elevate the table top relative to an underlying support surface or floor, the geared mechanism including multiple gears that rotate together;d) a gear box housing that envelops the geared mechanism and that is structurally connected to both the table top and each leg, said housing connecting to each leg at a position positioned below the geared mechanism;e) the geared mechanisms being simultaneously rotated during elevation and wherein load transfer between the table top and legs is via a said gear box housing; andf) wherein there are no connections below the gear box housing that span in a generally horizontal direction from one leg to another leg below said table top. 19. An elevating table apparatus, comprising: a) a table top providing an upper work surface and a lower surface;b) a plurality of table legs, each leg including leg members including an inner leg moving member and an outer leg member that has a bore that is receptive of the inner leg member, one of said leg members being stationary and non-elevating;c) a geared mechanism on the upper end portion of each leg that enables a user to elevate the table top relative to an underlying support surface or floor;d) each said geared mechanism including multiple gears that rotate together;e) each leg having a gear box housing that surrounds the geared mechanism and that extends circumferentially around and radially away from the geared mechanism, the housing being structurally connected to the table top at a first attachment area with a plurality of fasteners that extend through the housing into the table top;f) the housing being connected to a said leg at a second attachment area smaller than the first attachment area and wherein the housing spans between the first and second attachment areas;g) each gear box housing being connected to a leg below the geared mechanism, the gear box housing having an upper peripheral edge portion that is structurally connected to the table top, the peripheral portion extending radially beyond the diameter of the leg inner moving member, and the peripheral portion extending circumferentially around the geared mechanism;h) an externally threaded rod having an upper rod end that is attached to and that rotates with one of the gears, the rod extending from the gear box to an internally threaded nut that is attached to said stationary non-elevating leg member;i) wherein the rod engages the internally threaded nut so that the rotation of the rod effects an elevation of the table top; andj) wherein there are no connections below the gear box housing that span in a generally horizontal direction from one leg to another leg below said table top.
