A table comprising:

• a plurality of supporting rods, collars, retaining boards, supporting beams and bridge beams;
• and
• a cover board
• each of said supporting rods being formed with multiple annular locating grooves spaced apart at equal intervals and having a soft pad on a lower end of the supporting rods;
• each of said collars being composed of two conic semicircular plates tapered from a lower side to an upper side;
• a first side of each of the two conic semicircular plates being formed with a notch and a second side with a projection;
• an inner face of each of the two conic semicircular plates being formed with an annular rib;
• corners of each of the retaining boards being formed with a recessed arc;
• a bottom face of the cover board having a socket at each corner of the cover board;
• the collars being attached to the supporting rods by engaging the projection in the notch of each of the two conic semicircular plates with the annular rib of each of the two conic semicircular plates engaged in an annular locating groove of said locating grooves;
• the supporting beam having a linkage whose ends are each connected to a C-shaped conic fixing sleeve;
• a top edge of the linkage having two spaced apart recessed sections;
• wherein when assembled, the C-shaped conic fixing sleeves of the supporting beams are fitted over the supporting rods when engaged to the collars, the bridge beams are engaged to the linkages of the supporting beams when each end of the bridge beams are inserted into the two recessed sections, the retaining boards being positioned between the supporting rods with each recessed arc permitting the retaining boards to fit around the supporting rods and the C-shaped conic fixing sleeves of the supporting beams and rest on the linkages of the supporting beams and the bridge beams, and the top end of each of the supporting rods engaged in the socket of said cover board.
