how am i intended to use crafting for existing table blocks ?

[Chuunkyz]

i added this in the config :

"minecraft:fletching_table": {
  "type": "existing_block",
  "width": 1,
  "height": 3
}

but now how can i make recipes with it ?

"artis:minecraft_fletching_table_shaped" and "artis:fletching_table_shaped" are both invalid

Try simply using "minecraft:fletching_table_shaped"
