My object for the Object Library
table(...) takes four parameters
1) float tablePostLeftX
2) float tablePostRightX
3) float tablePostTopZ
4) float tablePostBottomZ

These are the positions of the table legs. This is assuming a normal coordinate system with a normal (down the z axis) camera view.
The size of the top of the table is: 
tablePostRightX-tablePostLeftX
tablePostTopZ-tablePostBottomZ
y=4*
Color of table legs is brown, top is white/
