I didn't use a table on my Lab. I taught Hold on the top of the kennel and Fetch on the ground. I trained my Airedale on an 8 ft. table. The club I belong to has a 16' ft. table. I don't use electronics and train by myself I think working without a table was faster. If you decide to try that way be sure to put some kind of weight inside the kennel, they are pretty easy to tip over when your dog starts trying to avoid training and by the time you have everything set up again the dog has decided he's won that round.
This a good article on F/F.
