I don't know if spook made it, but it seems possible. Peter described the table like this:
Notice the focus on Roshar which probably means the table was made at the time of SA, which happens just before era 2. And if spook really did have a 100 year rule where he was specifically studying hemalurgy, I think he could have the info to do it, except for the God metals but maybe marsh knew and told him? Who knows.
I think it's more likely the chart was made by some arcanist or probably khriss. (or maybe storming jasnah made idk)
