        --------
        Styler.format_index: Format the text display value of index labels.

        Notes
        -----
        This method assigns a formatting function, ``formatter``, to each cell in the
        DataFrame. If ``formatter`` is ``None``, then the default formatter is used.
        If a callable then that function should take a data value as input and return
        a displayable representation, such as a string. If ``formatter`` is
        given as a string this is assumed to be a valid Python format specification
        and is wrapped to a callable as ``string.format(x)``. If a ``dict`` is given,
        keys should correspond to column names, and values should be string or
        callable, as above.

        The default formatter currently expresses floats and complex numbers with the
        pandas display precision unless using the ``precision`` argument here. The
        default formatter does not adjust the representation of missing values unless
        the ``na_rep`` argument is used.

        The ``subset`` argument defines which region to apply the formatting function
        to. If the ``formatter`` argument is given in dict form but does not include
        all columns within the subset then these columns will have the default formatter
        applied. Any columns in the formatter dict excluded from the subset will
        be ignored.

        When using a ``formatter`` string the dtypes must be compatible, otherwise a
        `ValueError` will be raised.

        When instantiating a Styler, default formatting can be applied be setting the
        ``pandas.options``:

          - ``styler.format.formatter``: default None.
          - ``styler.format.na_rep``: default None.
          - ``styler.format.precision``: default 6.
          - ``styler.format.decimal``: default ".".
          - ``styler.format.thousands``: default None.
          - ``styler.format.escape``: default None.

        .. warning::
           `Styler.format` is ignored when using the output format `Styler.to_excel`,
           since Excel and Python have inherrently different formatting structures.
           However, it is possible to use the `number-format` pseudo CSS attribute
           to force Excel permissible formatting. See examples.

        Examples
        --------
        Using ``na_rep`` and ``precision`` with the default ``formatter``

        >>> df = pd.DataFrame([[np.nan, 1.0, 'A'], [2.0, np.nan, 3.0]])
        >>> df.style.format(na_rep='MISS', precision=3)  # doctest: +SKIP
                0       1       2
        0    MISS   1.000       A
        1   2.000    MISS   3.000

        Using a ``formatter`` specification on consistent column dtypes

        >>> df.style.format('{:.2f}', na_rep='MISS', subset=[0,1])  # doctest: +SKIP
                0      1          2
        0    MISS   1.00          A
        1    2.00   MISS   3.000000

        Using the default ``formatter`` for unspecified columns

        >>> df.style.format({0: '{:.2f}', 1: '£ {:.1f}'}, na_rep='MISS', precision=1)
        ...  # doctest: +SKIP
                 0      1     2
        0    MISS   £ 1.0     A
        1    2.00    MISS   3.0

        Multiple ``na_rep`` or ``precision`` specifications under the default
        ``formatter``.

        >>> (df.style.format(na_rep='MISS', precision=1, subset=[0])
        ...     .format(na_rep='PASS', precision=2, subset=[1, 2]))  # doctest: +SKIP
                0      1      2
        0    MISS   1.00      A
        1     2.0   PASS   3.00

        Using a callable ``formatter`` function.

        >>> func = lambda s: 'STRING' if isinstance(s, str) else 'FLOAT'
        >>> df.style.format({0: '{:.1f}', 2: func}, precision=4, na_rep='MISS')
        ...  # doctest: +SKIP
                0        1        2
        0    MISS   1.0000   STRING
        1     2.0     MISS    FLOAT

        Using a ``formatter`` with HTML ``escape`` and ``na_rep``.

        >>> df = pd.DataFrame([['<div></div>', '"A&B"', None]])
        >>> s = df.style.format(
        ...     '<a href="a.com/{0}">{0}</a>', escape="html", na_rep="NA"
        ...     )
        >>> s.to_html()  # doctest: +SKIP
        ...
        <td .. ><a href="a.com/&lt;div&gt;&lt;/div&gt;">&lt;div&gt;&lt;/div&gt;</a></td>
        <td .. ><a href="a.com/&#34;A&amp;B&#34;">&#34;A&amp;B&#34;</a></td>
        <td .. >NA</td>
        ...

        Using a ``formatter`` with ``escape`` in 'latex' mode.

        >>> df = pd.DataFrame([["123"], ["~ ^"], ["$%#"]])
        >>> df.style.format("\\textbf{{{}}}", escape="latex").to_latex()
        ...  # doctest: +SKIP
        \begin{tabular}{ll}
         & 0 \\
        0 & \textbf{123} \\
        1 & \textbf{\textasciitilde \space \textasciicircum } \\
        2 & \textbf{\$\%\#} \\
        \end{tabular}

        Applying ``escape`` in 'latex-math' mode. In the example below
        we enter math mode using the character ``$``.

        >>> df = pd.DataFrame([[r"$\sum_{i=1}^{10} a_i$ a~b $\alpha \
        ...     = \frac{\beta}{\zeta^2}$"], ["%#^ $ \$x^2 $"]])
        >>> df.style.format(escape="latex-math").to_latex()
        ...  # doctest: +SKIP
        \begin{tabular}{ll}
         & 0 \\
        0 & $\sum_{i=1}^{10} a_i$ a\textasciitilde b $\alpha = \frac{\beta}{\zeta^2}$ \\
        1 & \%\#\textasciicircum \space $ \$x^2 $ \\
        \end{tabular}

        We can use the character ``\(`` to enter math mode and the character ``\)``
        to close math mode.

        >>> df = pd.DataFrame([[r"\(\sum_{i=1}^{10} a_i\) a~b \(\alpha \
        ...     = \frac{\beta}{\zeta^2}\)"], ["%#^ \( \$x^2 \)"]])
        >>> df.style.format(escape="latex-math").to_latex()
        ...  # doctest: +SKIP
        \begin{tabular}{ll}
         & 0 \\
        0 & \(\sum_{i=1}^{10} a_i\) a\textasciitilde b \(\alpha
        = \frac{\beta}{\zeta^2}\) \\
        1 & \%\#\textasciicircum \space \( \$x^2 \) \\
        \end{tabular}

        If we have in one DataFrame cell a combination of both shorthands
        for math formulas, the shorthand with the sign ``$`` will be applied.

        >>> df = pd.DataFrame([[r"\( x^2 \)  $x^2$"], \
        ...     [r"$\frac{\beta}{\zeta}$ \(\frac{\beta}{\zeta}\)"]])
        >>> df.style.format(escape="latex-math").to_latex()
        ...  # doctest: +SKIP
        \begin{tabular}{ll}
         & 0 \\
        0 & \textbackslash ( x\textasciicircum 2 \textbackslash )  $x^2$ \\
        1 & $\frac{\beta}{\zeta}$ \textbackslash (\textbackslash
        frac\{\textbackslash beta\}\{\textbackslash zeta\}\textbackslash ) \\
        \end{tabular}

        Pandas defines a `number-format` pseudo CSS attribute instead of the `.format`
        method to create `to_excel` permissible formatting. Note that semi-colons are
        CSS protected characters but used as separators in Excel's format string.
        Replace semi-colons with the section separator character (ASCII-245) when
        defining the formatting here.

        >>> df = pd.DataFrame({"A": [1, 0, -1]})
        >>> pseudo_css = "number-format: 0§[Red](0)§-§@;"
        >>> filename = "formatted_file.xlsx"
        >>> df.style.map(lambda v: pseudo_css).to_excel(filename) # doctest: +SKIP

        -------
        Styler

        See Also
        --------
        Styler.format: Format the text display value of data cells.

        Notes
        -----
        This method assigns a formatting function, ``formatter``, to each level label
        in the DataFrame's index or column headers. If ``formatter`` is ``None``,
        then the default formatter is used.
        If a callable then that function should take a label value as input and return
        a displayable representation, such as a string. If ``formatter`` is
        given as a string this is assumed to be a valid Python format specification
        and is wrapped to a callable as ``string.format(x)``. If a ``dict`` is given,
        keys should correspond to MultiIndex level numbers or names, and values should
        be string or callable, as above.

        The default formatter currently expresses floats and complex numbers with the
        pandas display precision unless using the ``precision`` argument here. The
        default formatter does not adjust the representation of missing values unless
        the ``na_rep`` argument is used.

        The ``level`` argument defines which levels of a MultiIndex to apply the
        method to. If the ``formatter`` argument is given in dict form but does
        not include all levels within the level argument then these unspecified levels
        will have the default formatter applied. Any levels in the formatter dict
        specifically excluded from the level argument will be ignored.

        When using a ``formatter`` string the dtypes must be compatible, otherwise a
        `ValueError` will be raised.

        .. warning::
           `Styler.format_index` is ignored when using the output format
           `Styler.to_excel`, since Excel and Python have inherrently different
           formatting structures.
           However, it is possible to use the `number-format` pseudo CSS attribute
           to force Excel permissible formatting. See documentation for `Styler.format`.

            to all levels of an Index or MultiIndex which are not hidden.

        Returns
        -------
        Styler

        See Also
        --------
        Styler.format_index: Format the text display value of index or column headers.
        Styler.hide: Hide the index, column headers, or specified data from display.

        Notes
        -----
        As part of Styler, this method allows the display of an index to be
        completely user-specified without affecting the underlying DataFrame data,
        index, or column headers. This means that the flexibility of indexing is
        maintained whilst the final display is customisable.

        Since Styler is designed to be progressively constructed with method chaining,
        this method is adapted to react to the **currently specified hidden elements**.
        This is useful because it means one does not have to specify all the new
        labels if the majority of an index, or column headers, have already been hidden.
        The following produce equivalent display (note the length of ``labels`` in
        each case).

        .. code-block:: python

            # relabel first, then hide
            df = pd.DataFrame({"col": ["a", "b", "c"]})
            df.style.relabel_index(["A", "B", "C"]).hide([0,1])
            # hide first, then relabel
            df = pd.DataFrame({"col": ["a", "b", "c"]})
            df.style.hide([0,1]).relabel_index(["C"])

        This method should be used, rather than :meth:`Styler.format_index`, in one of
        the following cases (see examples):

          - A specified set of labels are required which are not a function of the
            underlying index keys.
          - The function of the underlying index keys requires a counter variable,
            such as those available upon enumeration.

        Examples
        --------
        Basic use

        >>> df = pd.DataFrame({"col": ["a", "b", "c"]})
        >>> df.style.relabel_index(["A", "B", "C"])  # doctest: +SKIP
             col
        A      a
        B      b
        C      c

        Chaining with pre-hidden elements

        >>> df.style.hide([0,1]).relabel_index(["C"])  # doctest: +SKIP
             col
        C      c

        Using a MultiIndex

        >>> midx = pd.MultiIndex.from_product([[0, 1], [0, 1], [0, 1]])
        >>> df = pd.DataFrame({"col": list(range(8))}, index=midx)
        >>> styler = df.style  # doctest: +SKIP
                  col
        0  0  0     0
              1     1
           1  0     2
              1     3
        1  0  0     4
              1     5
           1  0     6
              1     7
        >>> styler.hide((midx.get_level_values(0)==0)|(midx.get_level_values(1)==0))
        ...  # doctest: +SKIP
        >>> styler.hide(level=[0,1])  # doctest: +SKIP
        >>> styler.relabel_index(["binary6", "binary7"])  # doctest: +SKIP
                  col
        binary6     6
        binary7     7

        We can also achieve the above by indexing first and then re-labeling

        >>> styler = df.loc[[(1,1,0), (1,1,1)]].style
        >>> styler.hide(level=[0,1]).relabel_index(["binary6", "binary7"])
        ...  # doctest: +SKIP
                  col
        binary6     6
        binary7     7

        Defining a formatting function which uses an enumeration counter. Also note
        that the value of the index key is passed in the case of string labels so it
        can also be inserted into the label, using curly brackets (or double curly
        brackets if the string if pre-formatted),

        >>> df = pd.DataFrame({"samples": np.random.rand(10)})
        >>> styler = df.loc[np.random.randint(0,10,3)].style
        >>> styler.relabel_index([f"sample{i+1} ({{}})" for i in range(3)])

    '\<command><options>{display_value}', and this value is treated as the

    The most recent style forms the inner component, for example for styles:

    Sometimes latex commands have to be wrapped with curly braces in different ways:

     - `--rwrap`        : `\<command><options>{<display_value>}`
