There must be a lot of different tables installed in CD-25's. Here's Journey On's.
As Jay said above, there are 2 ea clips that hold the outboard edge of the table to the inboard side of the hull. I assume you've seen that. Journey On's table leg has a catch which allows the leg to fold, just a little. Drop the table slightly after you unlatch the table leg and (somehow) work the clips out of the fittings on the hull. It isn't easy and sometimes I've got one of the clips out and then managed to re-hook it whilst struggling to loosen the other. Keep working and you'll have success. Once the table is loose, fold the leg all the way back and have a beer.
Installing it is the inverse. Have a beer, unclip the leg slightly, struggle to install the clips into the respective holders, have another beer, finish the leg, have another beer and swear never to do that again.
In 5 years, I've managed to hold that chore to no more than 5 times.
