+1 for setting cell background color based on value. I'm sure you've thought of these already, but some use cases: (1) set colour based on mapping from (categorical) values to colours; (2) set colour using colour map, with user able to provide vmin, vmax, cmap and possibly normalize arguments to control value to colour transformation; (3) set colour using threshold on value, eg, red if > 5. Would be amazing if prettypandas could support these!

There already is colour-map support and min, max background support in the Pandas API http://pandas.pydata.org/pandas-docs/stable/style.html#Building-Styles. They have some neat functionality implemented. Since PrettyPandas subclasses pandas.core.Styler we get all that stuff for free.

I do think if a negative value colour indicator isn't built into pandas core then it definitely belongs here.

Also I think I should include those examples in the documentation so that people are aware

Wow, I didn't know about that, perfect! Good idea to include an example in prettypandas docs.

Please consider using axis='columns', axis='index' instead of axis=0, axis=1 to win over people who don't have numpy background. Pandas api supports this as well. See:
