1. A table top comprising:
an inner table top section and a perimeter section around a perimeter of the inner table top section;
the inner table top section consisting only of an inner section of a top plate and an inner section of a bottom reinforcing plate;
the top plate having a top surface and a bottom surface;
the inner section of the bottom reinforcing plate having a plurality of substantially uniformly distributed and integrally formed projections having a first height, with the bottom surface of the top plate attached to and supported by top surfaces of the projections;
the perimeter section of the table top including a downward flange around outer peripheral edges of the top plate, and
the perimeter section of the table top including an upward flange on the bottom reinforcing plate around outer peripheral edges of the bottom reinforcing plate, with the upward flange including a first substantially vertical surface and with the downward flange having a downward sloped surface and a second substantially vertical surface extending down from the downward sloped surface, the second substantially vertical surface overlying, parallel to and in contact with the first substantially vertical surface, and with the second substantially vertical surface forming an outboard edge;
the upward flange including an upward sloped surface and the first substantially vertical surface extending up from the upward sloped surface;
the upward flange and the downward flange in part forming an enclosed cavity having four sides and a second height greater than the first height; and
a single rectangular reinforcement frame inside of the cavity and extending continuously within the four sides of the cavity, and the single rectangular reinforcement frame extending continuously along the perimeter section around the inner table top section.
 
5. A table top comprising:
a first piece pivotally attached to a second piece, with each of the first and second pieces including:
an inner table top section and a perimeter section around a perimeter of the inner table top section;
the inner table top section consisting only of an inner section of a top plate and an inner section of a bottom reinforcing plate;
the top plate having a top surface and a bottom surface;
the inner section of the bottom reinforcing plate having a plurality of substantially uniformly distributed and integrally formed projections having a first height, with the bottom surface of the top plate attached to and supported by top surfaces of the projections;
the perimeter section of the table top including a downward flange around outer peripheral edges of the top plate, and
the perimeter section of the table top including an upward flange on the bottom reinforcing plate around outer peripheral edges of the bottom reinforcing plate, with the upward flange including a first substantially vertical surface and with the downward flange having a downward sloped surface and a second substantially vertical surface extending down from the downward sloped surface, the second substantially vertical surface overlying, parallel to and in contact with the first substantially vertical surface, and with the second substantially vertical surface forming an outboard edge;
the upward flange including an upward sloped surface and the first substantially vertical surface extending up from the upward sloped surface;
the upward flange and the downward flange in part forming an enclosed cavity having four sides and a second height greater than the first height; and
a single rectangular reinforcement frame inside of the cavity and extending continuously within the four sides of the cavity, and the single rectangular reinforcement frame extending continuously along the perimeter section around the inner table top section;
the first piece pivotally attached to the second piece by a first hinge at a first corner of the reinforcement frame of each of the first and second table top pieces, and by a second hinge at a second corner of the reinforcement frame of each of the first and second table top pieces.
