    Format an array for printing.

    ----------
    values

    float_format
    na_rep
    digits
    space
    justify
    decimal
    leading_space : bool, optional

        When an array as a column of a Series or DataFrame, we do want
        the leading space to pad between columns.

        When formatting an Index subclass
        (e.g. IntervalIndex._format_native_types), we don't want the
        leading space since it should be left-aligned.
