The Fletching Table has been in the game for years. The block has no real purpose in the vanilla game and is termed as a "Decoration Block". The Nock Enough Arrows mod adds new arrows into Minecraft. Most of them can be created using the Fletching table, giving the block a purpose. Fletching tables now even have their own dedicated GUI that you can use in order to create the variety of arrows added by this mod. Some of the arrows added by this mod and their special abilities are :

Pufferfish Arrow - Places a small Pufferfish where it hits.
Explosive Arrow - Creates a small explosion where the arrow hits.
Slime Arrow - Bounces 3 times when hitting a surface.
