Question about how to organize random tables

Hey everyone! I'm cross-posting this on a few subreddits to gather info.

I started making my own random tables for my rpg's because I enjoy doing this and the being surprised myself by what wacky stories emerge from them. But now I'm starting to have many tables and I don't know how to organize them to navigate efficiently through the page. I know about "the game master's box of unlimited adventure" of Jeff Ashworth but I don't own them. My question is : can someone broadly summarize the way the books are organized ?

I want to arrange the tables by theme but some of them overlap or I need to go from a table to another for a specific purpose (for exemple, If I create an npc, ask the oracle if they have a quest and the answer is yes, I go to the quest hook table, but then if the quest is to find an item, I need the item table). So I can't wrap my head around how to organize this mess into something coherent and mostly intuitive.

Do some of you have a good method to suggest (that does not require buying things) ?
