Ignore the datum zero and draw where you want.
Well I gave that a try using my simple table as an exercise.
by ignoring the datum I had an absolute nightmare try to move parts into contact with each other through the 3d space.
All I do is draw some guide lines with the ruler tool. If your table legs are 1000mm apart just draw guide lines to make a grid at that pitch and move your component to the intersection. you could even just draw a rectangle to size then move components to the corners and delete the rectangle afterwards.
There is more than one way to do most things in sketchup so whatever works for you.
