Table
When the rails get wet there is a good chance they will warp if you remove them right away, you'll want to leave the rails bolted to the slate and put at least a good size fan or two facing the table to ward off the saturation/good amount of air movement as well.. once the table is fairly dry/a day of drying with fans you can disassemble it and say your prayers,inspect and recover if table is not a loss....
On another note, call the insurance company
..
Best of luck
