Minecraft wiki entry for Furniture, associated text: Place 2 blocks above where you want your table, now create a 2 block deep hole below the blocks above your table (3 if you include the gap for the table which should already be there), get into the hole, look up and place 2 stairs facing each other on the bottom of them, get out the hole and fill it in, now remove the 2 blocks above the table, you now have a nice simple table.
