A round dowel fits into the round hole on top and bottom of the end piece and passes through the elongated hole on the table top. This allows the table top which is made of several boards glued together (acting as one big board) to move back and forth with expansion and contraction with the dowel going through the elongeated hole on the table top.
I hope that makes sense.
Also not that the end pieces dont 'float' as in loosely. They fit relatively snugly because the expansion and contraction is relatively slow and this slow and steady force can move with a good amount force.
