Not knocking OP's efforts as a nifty academic excercise -- good stuff. But MSI is a real world (admittedly MS) attempt at writing imperative instructions into relational tables.
Humble is about writing HTML tables, not database tables! :-)
I haven't tried developing MSI installers, so haven't experienced the horror.
One more area where I saw tables used for describing processes was keyword driven testing:

Didn't have enough experience with it so don't know if it is also horrific...
Sure, but in my experience the challenge of describing imperative instructions with tabular data (in general) makes the Object/Relational problem look one-dimensional.
