Follows #10250

For 0.17.1

• Nicer table styling for the pydata.org website
• Include a visual example in 0.17.1.rst
• remove doc/source/html-styling.html and find a way to include doc/source/html-styling.ipynb in the doc build (should use --template=basic)
• update print_versions
• update requirements_all.txt to include jinja

For 0.18.0 / Future

• sparsify MultiIndex repr (maybe push till 0.18)
• easy alignment styles Right align numbers in HTML repr of tables #12144
• Template modification: This is for things like wrapping base64 encoded values in img tags, urls, etc. flows into...
• Break the large template in Styler.template into smaller blocks. Let people extend that. We could (maybe) allow users to choose which template to use to render each column/cell with solving the template modification problem
• Truncated repr
• hook into pd.options, allow setting of default reprs with styles
• Refactor parts of Styler into a BaseStyler, maybe add a LaTeX styler (maybe deprecate / replace the to_html and to_latex methods; Jinja templates are much more pleasant to work with), xref CLN/API: implemented to_html in terms of .style #11700
• Categoricals / Boolens builtin stylings

will add more as we go.
