Hi, StyleFrame doesn't currently support MultiIndexed dataframes. I have started to implement it but got into a small issue due to the way pandas handle objects that are used in the MultiIndex.

Hi @DeepSpace2 you wrote "small issue", so we can expect this to be implemented in future, i understand this is not a showstopper?

Hello @DeepSpace2 any progress on this topic?

@urosdigital Hi, thanks for still showing interest in this. The "small" issue turned out to bigger issue due to the way pd.MultiIndex treats mutable objects. It uses an internal hash/cache, so the same object in the multiindex only exists once.

This is problematic for styleframe because each "cell" in the dataframe is an object with a value and style. Due to pd.MultiIndex caching what it believes to be similar objects, accessing and styling individual indexes/rows is not possible and styles are applied to the wrong rows.

I haven't figured a smart way around it.
