That would work great... put the coil on top of the table, and connect the 
RF ground of the coil (i.e. the bottom of the secondary) to the table. Make 
sure the table is grounded to a safety ground.  Doesn't need a big wire, 
it's just for protection if something "bad" happens (like the 110V primary 
wire falls off and touches the table the fuse or breaker blows, etc.).
