yeah, it took 2-3 days longer than expected since I was stubborn and
started reimplementing the C++ standard library instead of switching
targets and rewriting my code.

Sorry, I don't think it's possible (at my rate of coding at least) to
get something working that could generate those markdown tables in
Python, C++, or Rust. I'd estimate at least 2-3 days.

Sorry, I was under the impression that the plan was to build a program
for generating markdown tables, then we could both play around with it
and discuss the generated output. Since there are apparently questions
I haven't answered, would you please point me to them? I've kinda lost
track of where exactly they are.

right now. (actually probably tomorrow morning, since I'll be going to
bed soon since it's 1am).
