This is the script https://pastebin.com/ykQzdAqJ , now as the wiki says i named my script "LootTableTweaker"

and some of the items still spawn like the ender io gears and the capacitors etc, also i still get the ic2 ingots to spawn. i tested this spawning dungeon chests to see what loot to remove and it still spawns over and over and over. i even tried removing the ore using the oredict method as you can see in the script.

Thanks for the report, my mod is kind of trash tbh. I would recommend using another mod like https://minecraft.curseforge.com/projects/loottweaker until I can properly fix it.
