You are in the right place, but you are missing a cut scene. Clicking on the head on the table should trigger a cut scene where the statue in the room above moves to reveal some stairs.
Try deleting the files in the dynamic folders;
'
..\Beyond Divinity\Acts\Act1\Dynamic', '
..\Beyond Divinity\Acts\Act2\Dynamic', etc.
These folders are used as a cache for the game. Files are created / copied there from the save game folder when you load, and written / copied to those folders when you save a game. The files will be re-created as required the next time you start Beyond Divinity. If there was a corrupt file in those folders, deleting the files should fix the problem.
After that, try loading the save and hitting the lever again.
Are you comfortable hex editing? I could get the coordinates that would let you bypass the stuck statue, but you may miss a bit of experience that way.
Teleporting anywhere (via hex editor)EDIT:
You should get 11,664 experience points for clicking on the lever on the table and opening the stairs to the next room.
