Unlike all the other villager workstations, the fletching table has no use in the game (except as a workstation for the fletcher). I think that the fletching table should have the use of being able to tip arrows with different items such as tnt and fire charge. You should also be able to repair bows with string or sticks with it. There are many other ways you should be able to use it for. But these are the only uses I thought about. Anyone who is reading this can suggest other uses.
