Fletching tables were introduced to Minecraft with the 1.9 update. This block has been noticed by many players as a possible user interface. Players can observe this in spectator mode and conclude that an update to the table might include a clickable use, possibly involving arrows.
This is not part of vanilla Minecraft at the moment. However, there are some good uses for fletching table. These are the most important.
Fletching tables are different from other Minecraft blocks. They are great for decorating. They don't have a click function, so they can be used to spice things up or add character to a build.
In a pinch, all wooden blocks can be used as fuel in a smoker, furnace, or blast furnace. Although they are not the most useful fuel source, they can be used when players don’t have any coal or other resources. They can smelt 1.5 items in the furnace.
Fletching tables are best used as a job block. Fletching tables can be picked up by unemployed villagers who will trade.
