Event's Item Stacks and Player's Inventory

@SubscribeEvent
public void onItemCrafted(PlayerEvent.ItemCraftedEvent evt) {
    evt.player.inventory.addItemStackToInventory(new ItemStack(Blocks.DIRT, 64));
    System.out.println("random event fired");
}

This work's however, I'm wondering if there is a way to modify this to accept loot from a custom loot table. I'm not too familiar with loot table's and most of what I can find is older and for out of date versions and only handling loot chests.

is there a simple way of doing this or if there isn't please don't strain yourself however, I'd appreciate a point in the right direction if nothing else. thanks in advance. Also yes I know this is a bad example and will fire for every item crafted however I'm trying to work out what works first.
