The invention claimed is: 1. A collapsible one-piece table and dolly comprising: a stand-alone support frame; a handle adjustably connected to an upper portion of the support frame; a table rotatably connected to the upper portion of the support frame by a first set of hinges; expandable support means rotatably connected to the table and the support frame that gradually raise the table to a horizontal open configuration or assist with closing table to a vertical stowed configuration and rotate on ball studs for both the open or stowed configurations; a spring-activated release/locking mechanism, connected to one side of the support frame that, when manually-activated, releases the table to be raised by the expandable supports into a horizontal position or locks the table when it is manually-closed in the vertical stowed configuration; telescoping legs, rotatably connected to the table by a second set of hinges, that when manually deployed, use pivot levers to release/lock legs at selected height with audible sound when locked; wheels rotatably connected to a back side of a lower portion of the support frame that include a spring-actuated locking mechanism mounted on the support frame for each wheel; a four-sided dolly supporting plate with one side connected to a front side of the lower portion of the support frame; the three remaining sides of the supporting plate are connected on each side, by hinges, to corresponding, smaller flush-mounted plates; the three corresponding plates can be raised to a vertical position from the supporting plate, to interlock with each other and the support frame, to create a four-sided material containment box for secure transportation of goods by the combined table and dolly when table is in a stowed position; and supporting legs configured to support the dolly supporting plate. 2. The collapsible and combined table dolly of claim 1, wherein the flush-mounted plates comprise two lateral side plates of equal height and having a length, said length being less than a total length of a lateral edge of the supporting plate so as not to impede rotation of the wheels when lowered from the vertical position, along with a front plate, said front plate having a length equal to the length of a front edge of the supporting plate and a height equal to the height of said lateral sides. 3. The collapsible and combined table dolly of claim 2, wherein the the hinges that connect the flush-mounted plates to the supporting plate are limited in rotation such that said flush-mounted plates are flush with a top surface of the supporting plate when lowered from the vertical position, thereby increasing the area of the supporting plate. 4. The collapsible and combined table dolly of claim 3, wherein the sides fold up and through either clips or, by slots and matching rotating tabs, the sides can he secured together to form the three-sides of a box and the fourth side, to complete the box, is the slowed table top. 5. The collapsible combined table and dolly of claim 1, wherein the handle is configured to be at least one of adjustable and removable relative to the table. 6. The collapsible combined table and dolly of claim 1, wherein the handle further comprises spring loaded pins for at least one of adjusting a height of the handle and total removal of the handle. 7. The collapsible combined table and dolly of claim 1, wherein the handle further comprises manual pins and clips for at least one of adjusting a height of the handle and total removal of the handle. 8. The collapsible combined table and dolly of claim 1, wherein the releasing mechanism is foot-activated and spring actuated. 9. The collapsible combined table and dolly of claim 1, wherein the wheels further comprise spring-activated locking means that's foot-actuated, mounted on the support frame, to fix the position of the wheels. 10. The collapsible combined table and dolly of claim 1, wherein the wheels further comprise ball bearings configured to facilitate towing by a low-speed vehicle. 11. The collapsible combined table and dolly of claim 1, wherein the flush-mounted plates are comprised of at least one of wire mesh or solid material. 12. The collapsible combined table and dolly of claim 1, wherein the flush-mounted plates are flush to the level of the dolly supporting plate when lowered from the vertical position. 13. The collapsible combined table and dolly of claim 1, wherein the telescoping legs further include spring loaded pins configured to provide for additional height adjustment of the telescoping legs. 14. The collapsible combined table and dolly of claim 1, wherein the table can be made of wire mesh. 15. The collapsible combined table and dolly of claim 1, wherein the table is configured to support 150 pounds. 16. The collapsible combined table and dolly of claim 1, wherein the table is configured to include hinges that rotate the telescoping legs that when manually deployed, use pivot levers to release/lock legs at selected height with audible sound when locked into an extended position in open position and mounted or molded-in clips that lock the telescoping legs in collapsed, stowed position to bottom of table. 17. The collapsible combined table and dolly of claim 1, wherein with the handle removed, at least one of linking pins and linking notches or bands or clips can be configured to provide a secure interconnect of a first combined table and dolly to a second combined table and dolly in order to extend the size of the surface of the table. 18. The collapsible combined table and dolly of claim 1, wherein when the telescoping legs are retracted, the table closes into the vertical stowed configuration by manual pressure until the spring-activated release/locking mechanism that is configured to hold the table in the vertical stowed configuration is engaged. 19. The collapsible combined table and dolly of claim 1, wherein the expandable support means are at least one of hydraulic or gas-charged struts. 20. The collapsible and combined table dolly of claim 1, wherein with handles removed, a series of table/dollies can be linked together through notches and corresponding studs, or by clips or bands and corresponding studs to form one increased length or width table top. 21. The collapsible and one-piece table dolly of claim 1, wherein different table tops for specific tasks/uses could be used without sacrificing the design or interconnectability, wherein the tasks/uses are selected from the group comprising: a tool bench with bolted-on accessories; a wet sink for construction/outdoor use; multiple chamber steamer wells or a 55-gallon drum-style enclosed barbeque for catering use.
