Style not able to take formatters

[schwallie2]

When using the new CSS styling, there doesn't seem to be a way to add formatters for the numbers. So trying to make the number data display as $10,000 when using any styling options currently seems off the table.

I suppose the formatting should be expanded to cover all the functions in Styler not just .set_precision, so the following should take some kind of format={} kwarg that defines the format per column.

• .highlight_min
• .highlight_max
• .highlight_max
• .bar

This is partly implemented in #11667.

API wise it'd be best to have a dedicated method for this, something like .format that takes a list of dictionaries mapping column to a python string formatting spec.

Agree with the .format being better than implementing this everywhere. Can
we reuse formatters from to_HTML?

Yeah we should match that API if possible.

I think our best bet implementation is to build up a more complicated dictionary outside of the template that contains another field with the formatted / to be displayed value. We'll look for that field in the template.
