Was watching an episode the other day when Granny couldn't get the green tablecloth off of the Fancy Eatin Table, and I noticed there were no pockets in it. I also remember another episode where it was mentioned that the pockets would come in handy for scraps, so there must have been pockets in that one.
Could there possibly have been 2 tables used at one point, or did I just miss the pockets even though I was specifically looking for them?

Yeah - I remember the "Fancy Eatin' Table" in the "Billy-ard Room". Granny or Jed points to the moosehead on the wall and say "That must be a billy-ard!". And they called the cues "pot passers". I don't know about the pockets or balls, but there was an episode when the hustler (Phil Silvers?) gets hustled himself at this same table ("this is like ricochet shooting").

it was a rhinoserass head that they thought was a "billy-ard"'
And, it wasn't "the hustler" ("shifty" Shafer but the Clampetts called him "honest John") who got hustled at the "billy-ard" table. It was Mrs Drysdales father; Lionel Farqua who tried to hustle Jed and Jethro at it.

Did they ever find out what that table really was?

Mrs. Drysale's dad was Lowell Redlings Farquhar (not "Lionel").

Obviously Daddy Farquhar spilled the beans when he said to Jed and Jethro something like "Did you know that you can play a game on this table?" But it may have been left unclear as to whether the Clampetts ever realized that the table was made for playing games -- and not for eating. So the answer to your question liane could be a qualified "yes."

I think it was good that they kept up the billiard table gag for so many years.

By contrast, early on the Clampetts are totally unfamiliar with telephones -- while later it's revealed that Granny supposedly had used a party-line phone years earlier, back home. So in that case, even though it was worked for a lot of gags, the continuity was thrown out the window.

This is kinda OT, but I've always wondered if they thought the billiard room was the formal dining room, what did they think the REAL formal dining room was? A house that size would surely have dining room somewhere.

In the floorplan of their mansion the formal dining room is right before you get to the pantry ouside the kitchen and it connects to the parlor.
