11 and bottom panel 12 the internal fixed part 14 is set at the edge between the top panel 11 and bottom panel 12 with its height larger than the thickness of paper honeycomb core therefore the outer edge of such table top panel is thicker than the middle plate which may not only enhance the strength of edge of table top panel but also looks beautiful satisfying the requirements for a general top panel the connection structures of side top panel and bottom panel are the same as that in embodiment 3 i e a protruding section is set at the side of bottom panel embodiment 6 as shown in fig8 the table top panel is composed of top panel 11 bottom panel 12 honeycomb paper core 13 and internal fixed part 14 the edge of top panel 11 bends downwardly the upwardly bending edge of bottom panel 12 forms a cavity and then bends upwardly forming a close space filled with paper honeycomb core which is bonded to top panel 11 and bottom panel 12 or either of them the internal fixed part 14 is set inside the cavity of the bottom panel 12 below the honeycomb paper at the edge of top panel likewise the thickness of outer edge of table top panel in this structure is larger than that in the center making it beautiful in appearance furthermore the position of such internal fixed part will not certainly be set in the outer edge as long as a cavity in.
