A folding table base is provided which includes a mounting plate adapted to be secured to the bottom of a table. A hinge plate is hingedly connected to the side of the mounting plate. The hinge plate is adapted to pivot between a first position and a second position. A leg is secured to the hinge plate and extends generally orthogonal thereto. A latching mechanism is secured to the bottom of the table. The latching mechanism includes a latch mounting plate and a pull latch. The pull latch being slidably mounted on the latch mounting plate such that the pull latch is operable between a latched position and an unlatched position. The latching mechanism engages the hinge plate when the pull latch is in the latched position and disengages the hinge plate when the pull latch is in the unlatched position.

1. A table having a table top and at least one laterally adjustable leg and foot to permit the conversion of the table configuration, comprising:first adjustment means at the upper end of said leg for connecting said leg to said table top while permitting adjustment of the lateral position of said leg relative to said table top, said first adjustment means including means for holding said leg in a selected lateral position relative to said table top, andsecond adjustment means at the lower end of said leg for connecting said leg to said foot while permitting adjustment of the lateral position of said foot relative to said leg, said second adjustment means including means including means for holding said foot in a selected lateral position relative to said leg,wherein each of said first and second adjustment means includesan outer member carrying at least one tab having a movable end and a fixed end, said fixed end being connected to the outer surface of said outer member proximate one end thereof, said movable end having means for protruding inwardly through said member; andan inner member having an end portion telescoped within said outer member, said inner member having at least one aperture for receiving said protruding means when it protrudes inwardly through said outer member. 2. The table of claim 1 wherein said outer and inner members are tubular members. 3. The table of claim 1 wherein said outer member has a transverse aperture extending through at least one side thereof proximate the upper end thereof, said protruding means on said tab is adapted to extend inwardly through said aperture, and said inner member has a plurality of transverse apertures for receiving said protruding means when it protrudes through said transverse aperture in said outer member. 4. The table of claim 1 wherein said tab is a spring tab. 5. The table of claim 1 wherein said protruding means comprises a pin. 6. A method of laterally adjusting the position of at least one leg of a table, said method comprising:providing said leg with a lateral adjustment mechanism, said mechanism connecting said leg to said table, said mechanism including at least one pair of telescoping inner and outer tubular members having transverse apertures extending therethrough, said inner member having a plurality of said apertures spaced along a portion of the length thereof, and said outer member having a spring tab mounted on the outer surface thereof, said spring tab having a fixed end being connected to the outer surface of said outer member and a movable end having means for protruding inwardly through said transverse apertures; andmoving said inner member relative to said outer member to adjust the lateral position of said table and to register one of said plurality of apertures in said inner member with said aperture in said outer member. 7. The method of claim 6 which includes telescoping a sleeve over said spring tab to hold said protruding means in place within said transverse apertures of said inner and outer tubular members. 8. The method of claim 7 wherein the relative movement between said sleeve and said outer member is limited by engaging said outer member with a flange on one end of said sleeve. 9. The method of claim 8 wherein said flange extends inwardly from the upper end of said sleeve. 10. A method of converting the configuration of a table having a table top and at least one laterally adjustable leg and foot between a T configuration and an L configuration, comprising:adjusting the lateral position of said leg relative to said table top via a leg lateral adjustment mechanism by moving the upper end of said leg to a selected lateral position relative to said table top and then holding said leg in said selected lateral position, andadjusting the lateral position of said foot relative to said leg by moving said foot to a selected lateral position relative to said leg via a foot lateral adjustment mechanism and then holding said foot in said select ed lateral position, said foot being secured to a lower end portion of said leg. 11. A table base comprising:a leg sliding mechanism mechanically secured to the bottom of a table, said leg sliding mechanism includinga leg plate,a leg extending generally orthogonal thereto, said leg sliding mechanism being adapted to slide between a first position and a second position such that said leg is laterally adjustable with respect to the table, said leg being secured to said leg plate and extending generally orthogonal thereto,a pair of angle mounts secured to the bottom of said table, anda pair of hollow pipes and a pair of rods, said pair of rods being respectively disposed in said pair of hollow pipes and secured between said pair of angle mounts, said pair of hollow pipes being secured to said leg plate such that said pair of hollow pipes are generally parallel with respect to each other, said pair of hollow pipes adapted to slide back and forth on said pair of rods; anda locking mechanism for securing said leg sliding mechanism in a particular position. 12. The folding table base of claim 11, wherein said pair of rods are identical in construction. 13. The folding table base of claim 11, wherein said pair of hollow pipes and said pair of rods are secured in a particular position by a pin. 14. The folding table base of claim 11, wherein said pair of hollow pipes and said pair of rods are secured in a particular position by a spring tab. 15. A table base comprising:a leg sliding mechanism mechanically secured to the bottom of a table, said leg sliding mechanism including a leg extending generally orthogonal thereto, said leg sliding mechanism being adapted to slide between a first position and a second position such that said leg is laterally adjustable with respect to the table;a mounting plate adapted to be secured to the bottom of a table, said mounting plate having a side;a hinge plate hingedly connected to said side of said mounting plate, said hinge plate being adapted to pivot between an open position and a closed position; anda latching mechanism secured to the bottom of said table, said latching mechanism including a pull latch that engages said hinge plate when said pull latch is in a latched position and disengage said hinge plate when said pull latch is in an unlatched position,wherein said latching mechanism includes a latch mounting plate, said pull latch being slidably mounted on said latch mounting plate such that said pull latch is operable between said latched position and said unlatched position, said latching mechanism engaging said hinge plate at two displaced locations when said pull latch is in said latched position.
