How can user macros and packages be included in the latex rendered in markdown cells in ipython?
e.g.:
\usepackage{amssymb}
\newcommand{kms}{\ensuremath{\mathrm{km~s}^{-1}}
回答1:
It is possible to define macros in cells with markdown. Just put the \newcommand between $'s:
$\newcommand{kms}{{\mathrm{km~s}^{-1}}}$
(Note that I removed the \ensuremath command, as it is not accessible.)
In any following statement (in the whole notebook) you can call the macro (in a markdown cell only, of course):
$\kms$
I do not know a way to include extra packages :( If you ever learn how, I would also encourage you to use the siuntx package to format units.

The Html notebook use mathjax to render LaTeX, I suggest reading its doc to know wether it is possible and how.
