Minecraft loot table 1.14.4

I am in need to the answers to the following questions about loot tables in 1.14.4.

• What is the command to spawn in your custom loot table chest
• Wheres the directory to put the custom loot table in the .minecraft folder
• A working loot table generator for the latest version of Minecraft

p.s If I have got the wrong tags or theres another question on going that can help. I am truly sorry

1. /give @p chest{BlockEntityTag:{LootTable:"custom_namespace:loot_table.json"}} or /setblock ~ ~ ~ chest{LootTable:"custom_namespace:loot_table.json"}
2. .minecraft/saves/nameOfWorld/datapacks/datapack_name/data/custom_namespace/loot_tables
3. Loot Table Generator for Minecraft

You need to create a custom namespace for your loot table (the above assumes its custom_namespace) and also create a pack.mcmeta file in the "datapack_name" folder. The command is for a loot table called loot_table.json. To specify a loot table in a folder, use custom_namespace:folder/loot_table.json.
