How do I use my loot table for my chests?

So I've created a loot table and I wanted to use it for the chests in my randomly generated dungeons.

The problem is I can't seem to find anything that tells me how I do this.

I checked the wiki page for loot tables and it doesn't say how

I check the page for 2020.1's release and it only mentions that you can use loot tables for structure chests, not how

and I can't seem to find any recent forum topics about this. 

If anyone knows how to do this then please let me know.

Thank you for your time.
