How to use the xlwings.main.Sheet function in xlwings

Defaults to the Workbook that was instantiated last or set via ``Workbook.set_current()``.

        Examples
        --------
        >>> Sheet.all()
        [, ]
        >>> [i.name.lower() for i in Sheet.all()]
        ['sheet1', 'sheet2']
        >>> [i.autofit() for i in Sheet.all()]
