Quark allows you to define another loot table for when it generates it's dungeons, however, if you wish to use an alternative loot table that hasn't been loaded yet, you're out of luck.
This mod will register any .json files in {minecraft}/config/loot_table_loader/ as new loot tables.
So if you put a file in there say, quark_dungeon.json, it will be registered and available as "loot_table_loader:quark_dungeon"
You can then spawn in an example chest with your new loot table using
/setblock ~ ~2 ~ minecraft:chest 1 0 {LootTable:"loot_table_loader:quark_dungeon"}
Only servers (dedicated and integrated) are required to have this mod installed.
