     An inner lining for the tabletop connecting with the other parts or for strengthening the structures, which is arranged in the positions where need to connect or strengthen between the top plate and bottom plate. 
     The inner lining covers the honeycomb core completely around the honeycomb plate, the cross section of the inner lining is U-shaped; the nut welded on the top surface of cross plate of the U-shaped inner lining, and the cross plate has a second hole which matches the threaded hole of the nut. 
     The legs are pipe fittings, and there is a stator fixed on the topside or upper end of the legs, the stator has a connecting hole; the bolt head is fixed on the bottom of the stator, and the bolt shank passes through the connecting hole and protrudes out the top surface of the leg. 
     The legs are pipe fittings, and there is a connected slice fixed on the bottom side of the legs, the connected slice having an inserted hole. 
     The bottom of the tabletop has an equal number of first holders to the number of the legs, the legs are removably connected in the first holders. The bottom of the tabletop has second holders, and the tools are fixed removably connected in the second holders detachably. 
     By the above-mentioned description of the invention, compared with the prior art, the present invention has advantages as follows: 
     Firstly, the table with combined and upstanding legs, wherein the connecting positions connected with the top of legs by thread connection, and the legs have inserted part, through the rotation of the leg pipe by the tool inserted to inserted part, the threads of the leg pipe and the tabletop will connect together tightly to let the leg pipes lock with the corresponding connecting positions in the bottom of tabletop respectively. 
     Secondly, the table with combined and upstanding legs is light, simple-structure and is convenient to assemble or disassemble the legs and tabletop; 
     Thirdly, the tool has handle part and insert-part, which make the assembly and disassembly of the legs with tabletop be very easy and convenient; 
     Fourthly, the connection position comprising a nut embedded in the tabletop, the screw hole of the nut exposed in the bottom of the tabletop, thus the connection of the nut and the tabletop is firm; the top of the legs has an embedded bolt, the screw of the bolt protrude out the top surface of the legs, thus the connection of the bolt and the leg is firm; the connection of the bolt and the nut is convenient. 
     Fifthly, the tabletop is a composite plate comprising a top plate, a bottom plate and a honeycomb, wherein the inner lining is for the tabletop to connect with the other parts or to strengthen the structures, the nut fixed on the inner lining which make the connection of the tabletop and the other parts, feature high-strength, convenient-assembly, nice-look, lightweight; 
     Sixthly, the bolt head is fixed on the bottom of the stator, and the bolt shank extends through the connecting hole and protrudes out the top surface of the leg, thus the connection of the bolt and the leg is firm and is convenient to detach the bolt and leg. The connection of the bolt and the nut is convenient; 
     Seventhly, the plug has inserted hole, the connection of the plug and legs is firm, and convenient to assemble them; 
     Eighthly, the legs fixed in the first holder detachably and the tool fixed in the second holder detachably, thus the table occupy smaller space after folding and is easy to be carried out.
