Re: About using dash line in markdown file

TeX math is parsed by the texmath library (jgm/texmath on GitHub)

You could submit an issue there. Currently there is no support for lines in matrices.

Actually, there's an open PR that may give you what you need.
https://github.com/jgm/texmath/pull/168
Unfortunately it was never completed, even though the changes needed are minor.
