The Worksheet Class
===================

.. class:: Worksheet(sheetname, parent_book)
  
   This is a class representing the contents of a sheet in a workbook.
   
.. WARNING:: You don't normally create instances of this class
   yourself. They are returned from calls to :meth:`Workbook.add_sheet`

.. method:: Worksheet.write(r, c, label="", style=Style.default_style)

   This method is used to write a cell to a Worksheet..
   
   :param int r:
      	The zero-based number of the row in the worksheet to which the cell should be written.

   :param int c:
      	The zero-based number of the column in the worksheet to which the cell should be written.
		
   :param str label:
    	The data value to be written.
    	An int, long, or decimal.Decimal instance is converted to float.
    	A unicode instance is written as is.
    	A str instance is converted to unicode using the encoding (default: 'ascii') specified
    	when the Workbook instance was created.
    	A datetime.datetime, datetime.date, or datetime.time instance is converted into Excel date format
    	(a float representing the number of days since (typically) 1899-12-31T00:00:00,
    	under the pretence that 1900 was a leap year).
    	A bool instance will show up as TRUE or FALSE in Excel.
    	None causes the cell to be blank -- no data, only formatting.
    	An :class:`Formula` instance causes an Excel formula to be written.

   :param style:
    	A style -- also known as an XF (extended format) -- is an XFStyle object, which encapsulates
    	the formatting applied to the cell and its contents. XFStyle objects are best set up using the
    	:func:`easyxf` function. They may also be set up by setting attributes in
    	Alignment, Borders, Pattern, Font and Protection objects
    	then setting those objects and a format string as attributes of an XFStyle object.
