Many good suggestions have been made for removal of the table but you do have to remove the compression post.
The first thing to remember, have the boat out of the water. Some have tried in the water and they got water in the boat.
Remove the two plates at the base of the compression post inside the cabin which some where glued in with marine sealant or screwed in on the early H 26 boats. The two screws mentioned t0 be removed at the base of the compression post are #10 screws. On later models of the 26 and 260 they were not installed as they were not needed but those wiith no screws in the holes is a source for a leak. (Install 2 #10 screws with 5200. ) They are aft and forward at the base of the compression post.
Attach a runner line to the cascade line or keel line thru the mast compression post. It is easier to pull with a runner line in place the keel uplift or someitmes referred to as the cascade line when the compression post is put back on.
The compression post was sealed with 5200 which is hard to remove. I use to use a thin blade scraper to get it under the base on top or deck trying to cut it. I would go back with 5200 versus 4200 or silicon.
If sanding the table, be very carful as it is a lament style table with an 1/8 inch top cover.
