     FIELD OF THE DISCLOSURE 
     The present disclosure relates to a table panel, and in particular relates to a table panel having a combination of a top panel and a bottom panel. 
     BACKGROUND OF THE DISCLOSURE 
     Plastic table panels have the advantages of being light weight and low cost, especially plastic suction panels that comprise a top panel and a bottom panel. A thickness of a plastic suction panel is only about 1-2 mm. Therefore, the strength of the plastic suction panel comprising the top panel and the bottom panel is often weak. In order to enable the plastic suction panel to meet strength requirements when the plastic suction panel has a small thickness, it is conventional that a honeycomb structure is disposed on the plastic suction panel, a reinforcing bar is disposed under the table panel, or a metal frame is disposed around the table panel. 
     When the metal frame is disposed for reinforcing, since the thickness of the plastic suction panel is small, the side of the plastic suction panel is soft and easy to tilt up. Therefore, even in case that the plastic suction panel and the metal frame need to be bonded together by glue, so sides of the plastic suction panel cannot be nicely fit to sides of the metal frame. 
     In summary, the assembly of the plastic suction panel and the metal frame needs glue for bonding, and the production workshop needs to add a glue coating process. Therefore, the production cost is increased. In addition, the size of the table panel is large, and the glue coating process is manually performed, resulting in a heavy workload. 
     BRIEF SUMMARY OF THE DISCLOSURE 
     The present disclosure provides a table panel, which is convenient to assemble to solve deficiencies of the existing techniques and to improve deficiencies related to a plastic side edge of the existing combination table panel being difficult to be secured. 
     In order to solve the technical problems of the present disclosure, a technical solution of the present disclosure is as follows. 
     A table panel comprises a top panel, a bottom panel, and a metal frame. The bottom panel comprises a honeycomb structure, a periphery of the top panel is disposed with a downward folding edge, the metal frame is disposed on a bottom of the bottom panel and is disposed along a periphery of the bottom panel, an inner side surface of the downward folding edge of the top panel abuts the metal frame, a lower end of an outer side surface of the metal frame is disposed with a connecting piece extending downward, the connecting piece is outwardly folded from a bottom of the downward folding edge of the top panel to define a pressing edge configured to be buckled to an outer side of the bottom of the downward folding edge, and the pressing edge is secured to the downward folding edge by riveting. 
     In a preferred embodiment, the metal frame and the connecting piece are integrally formed by bending a metal sheet. 
     In a preferred embodiment, the top panel is bonded to the bottom panel, the bottom panel is disposed with a honeycomb structure, and the honeycomb structure is made by plastic suction. 
     In a preferred embodiment, an outer periphery of a top surface (i.e., the downward folding edge) of the top panel is disposed with a locking step retracting inward, and the locking step corresponds to the connecting piece. When two table panels are stacked up and down, the connecting piece of an upper table panel of the two table panels is disposed in the locking step of a lower table panel of the two table panels. 
     In a preferred embodiment, a height of the locking step corresponds to a height of the connecting piece. When the two table panels are stacked up and down, a bottom of the metal frame of the upper table panel abuts a top surface of the top panel of the lower table panel. 
     Compared with the existing techniques, the technical solution has the following advantages. 
     1. The lower end of the outer side of the metal frame is disposed with a connecting piece, and the bottom of the connecting piece is folded to form a pressing edge that buckles to the outer side of the bottom of the downward folding edge, so that the downward folding edge is fastened to the connecting piece by the pressing edge. The downward folding edge and the metal frame are firmly connected, thereby simplifying the assembly process of the table panel and making it easy for automated production. 
     2. The downward folding edge is disposed on the outer side of the metal frame and the connecting piece. Since the connecting piece is below the metal frame, the height of the downward folding edge needs to be greater than the height of the side of the metal frame. That is, the presence of the connecting piece increases the height of the downward folding edge and thus increases the thickness of the side of the table panel, which greatly increases a thickness effect of the table panel. 
     3. The outer edge of the top surface of the top panel is disposed with a locking step extending inward. When two tables are stacked up and down, the connecting piece of the upper table panel is disposed in the locking step of the lower table panel. The structure is more stable, and the height of the stacked table panels can be effectively reduced.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Referring to  FIGS. 1-5 , a table panel comprises a support panel  10  and a metal frame  20 . A periphery of the support panel  10  is disposed with a downward folding edge  11 , and the metal frame  20  is disposed on a bottom of the support panel  10  and is disposed along the periphery of the support panel  10 . An outer side surface of the metal frame  20  abuts an inner side surface of the downward folding edge  11 . A lower end of the outer side surface of the metal frame  20  is disposed with a connecting piece  21  extending downward, and a bottom of the connecting piece  21  is outwardly folded from a bottom of the downward folding edge  11  to define a pressing edge  22  configured to be buckled to an outer side of the bottom of the downward folding edge  11 . The pressing edge  22  is secured to the downward folding edge  11  by riveting. The connecting piece  21  and the pressing edge  22  define a hook structure  23  with an opening  231  facing upward, and the downward folding edge  11  is disposed in the hook structure  23 . 
     The metal frame  20  is secured to the support panel  10  due to the pressing edge  22  being punched and riveted to the downward folding edge  11 , and the structure is stable. 
     The metal frame  20  and the connecting piece  21  are integrally formed by bending a metal sheet, which have good deformability and is convenient for pressing, bending, punching, and riveting. It is obvious that the connecting piece  21  can also be formed separately from the metal frame  20  and then be welded to the metal frame  20 . Therefore, the metal frame  20  can be made of a hollow steel pipe. 
     The support panel  10  comprises a top panel  10 - 1  and a bottom panel  10 - 2 . A periphery of the bottom panel  10 - 2  abuts an upper surface of the metal frame  20 , and a periphery of the top panel  10 - 1  is folded downward to define the downward folding edge  11 . In some embodiments, the top panel  10 - 1  is bonded to the bottom panel  10 - 2 , and the bottom panel  10 - 2  comprises a honeycomb structure. The top panel  10 - 1  and the bottom panel  10 - 2  are made of a plastic flat board having a thickness of about 1 mm. Traditional top panels are bonded to bottom panels at side surfaces since the plastic flat board is thin, is easily deformed, and periphery shaping is difficult due to a preset temperature during deforming and manufacturing. However, in the present disclosure, the lower end of the outer side surface of the metal frame  20  is disposed with the connecting piece  21  extending downward to enable the downward folding edge  11  to be disposed in an inner side of the pressing edge  22  of the connecting piece  21 , and then the pressing edge  22  is punched and riveted to enable the pressing edge  22  to abut a lower edge of the downward folding edge  11 . A side of the table panel is well protected due to a well shape provided by the connecting piece  21 . 
     An outer edge of a top surface (i.e., the downward folding edge  11 ) of the top panel  10 - 1  is disposed with a locking step  12  retracting inward, and the locking step  12  corresponds to the connecting piece  21 . When two table panels are stacked up and down (i.e., in a vertical direction), referring to  FIGS. 5-6 , the connecting piece  21  of an upper table panel is disposed in the locking step  12  of a lower table panel. In some embodiments, a height of the locking step  12  corresponds to a height of the connecting piece  21 . When the two table panels are stacked up and down, a bottom of the metal frame  20  of the upper table panel abuts the top surface of the top panel  10 - 1  of the lower table panel. 
     The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
