It all depends what is going to be put on the table. If it is for light duty simply gluing with PVA (Titebond ultimate?) would probably be fine. If it’s going to have a heavy weight (an old TV?) on it for a long time you might find there is some creep.
Three solutions to this: Use Cascamite (which has a nice long open time too), or use loose tenons (biscuits or Dominos) or a zig-zag joint if you have a router table:
I used to have an Axminster White biscuit jointer (no longer available) but upgraded to a Domino which I love. Nothing wrong with a biscuit jointer but Dominos are stronger.
Incidentally in the thread was a link to the Plano clamps; I have them and they are dreadful. I’m in Cornwall and if you can collect you can have three and the rail for free. Hardly used (twice?). PM me if interested.
