Currently Styler has the
applyandapplymapmethods to perform conditional styling on the data elements.Recent additions to
Styler.set_table_stylesallows styling of index and column headers if the key-labels are directly specified. But this solution cannot work with LaTeX, nor excel output, and is obviously not conditionally applied.This PR adds the mechanics to perform conditional styling on per level index labels
