    Support various export formats for the table data.

    `ExportMixin` looks for some attributes on the class to change it's behaviour:

    Attributes:
        export_name (str): is the name of file that will be exported, without extension.
        export_trigger_param (str): is the name of the GET attribute used to trigger
            the export. It's value decides the export format, refer to
            `TableExport` for a list of available formats.
        exclude_columns (iterable): column names excluded from the export.
            For example, one might want to exclude columns containing buttons from
            the export. Excluding columns from the export is also possible using the
            `exclude_from_export` argument to the `.Column` constructor::

                class Table(tables.Table):
                    name = tables.Column()
                    buttons = tables.TemplateColumn(exclude_from_export=True, template_name=...)
