ENH: Index Left Alignment Option in a DataFrame
I wish I could align the contents of the index in a DataFrame to the left.

I could set the index as a column, and then hide the remaining index. This is not ideal, because I'd like to keep the pandas dataframe index formatting (i.e. bolding). Currently, it is possible to left align the columns within dataframes, just not the index.
