There are some tables that I will treat as a List and thus pluck ideas from (like 100 random NPC traits/adventure seeds/dungeon dressing) but I can never imagine myself using one as a random table. I've always found random tables to be... uninteresting at best.
Why? This is going to sound odd, but I don't like the idea of randomness. Yes, I'm aware RPGs use dice which are at their core random, but the dice are used as a fair way to answer the question "Does this act succeed?" It theoretically the same is if all tasks were resolved with paper-scissor-rock.
When dealing with treasure, or monsters, or really anything, I prefer there to be intelligent design used - everything is there for a reason. That treasure is there because someone put that amount in there, not 'well the chest is locked and trapped but hey there's a silver spoon in it". If I'm fighting a monster I want the DM to have chosen that monster and that encounter, and not for it to be just whim. The same with DMing - I prefer to have a conscious choice and intention for everything. The PCs find that magic item because I intended for them to have it (but then, I don't believe in selling magical items, so things they will solves two issues with one move).
Chance is sort of the opposite, for me, of a Story. Sure, the illusion of chance is there, but it's not real. Randomness is chaotic and I don't like chaos. I've never seen anything "random" be positive at all. Order (or intentional design) is far more comforting and, IMO, feels more real.
