    A writer class for Pandas DataFrame format.

        :Example:
            :ref:`example-pandas-dataframe-writer`

    .. py:attribute:: import_pandas_as
        :type: str
        :value: "pd"

        Specify ``pandas`` module import name of an output source code.

    .. py:attribute:: import_numpy_as
        :type: str
        :value: "np"

        Specify ``numpy`` module import name of an output source code.

    .. py:method:: write_table

        |write_table| with Pandas DataFrame format.
        The tabular data are written as a ``pandas.DataFrame`` class
        instance definition.

        :raises pytablewriter.EmptyTableNameError:
            If the |table_name| is empty.

        :Example:
            :ref:`example-pandas-dataframe-writer`

        .. note::
            Specific values in the tabular data are converted when writing:

            - |None|: written as ``None``
            - |inf|: written as ``numpy.inf``
            - |nan|: written as ``numpy.nan``
            - |datetime| instances determined by |is_datetime_instance_formatting| attribute:
                - |True|: written as `dateutil.parser <https://dateutil.readthedocs.io/en/stable/parser.html>`__
                - |False|: written as |str|
