I'm trying to make my own loot table, but for some reason, it just isn't working. I got it to work once when I was testing how the json file worked, but I haven't been able to get to work since

Spoiler

Forge requires that each loot pool in mod loot tables specifies a "name" property with a name that's unique to the loot table.

 

This is so that mods can modify/remove loot pools in LootTableLoadEvent.

Ok, that's why. Thanks!

I just updated it with the code I originally wanted and I get the enchanted book, but it doesn't have an enchantment, I figured that the following would have worked

{
    "pools": [
        {
			"name":"main",
            "rolls": 1,
            "entries": [
                {
                    "type": "item",
                    "weight": 100,
                    "name": "enchanted_book",
					"functions": [{
						"function":"enchant_randomly"
					}]
                }
            ]
        }
    ]
}

But I just get a blank enchanted book

You need to use minecraft:book, not minecraft:enchanted_book for the enchant_randomly function.
