创建excel文件 Create a workbook
There is no need to create a file on the filesystem to get started with openpyxl. Just import the Workbook class and start work:
开始使用openpyxl时，无需在文件系统中创建文件，只要导入workbook类就可以了：

>>> from openpyxl import Workbook
>>> wb = Workbook()
A workbook is always created with at least one worksheet. You can get it by using the Workbook.active property:
至少有一个工作表在工作簿创建后,可以通过Workbook.active属性来定位到工作表：

>>> ws = wb.active
Note
This is set to 0 by default. Unless you modify its value, you will always get the first worksheet by using this method.
该工作簿的默认索引是从0开始。除非索引值被修改，否则使用这个方法将总是获取第一个工作表。

You can create new worksheets using the Workbook.create_sheet() method:
可以使用Workbook.create_sheet()方法来创建新工作表

>>> ws1 = wb.create_sheet("Mysheet") # 插入到最后 (默认)

>>> ws2 = wb.create_sheet("Mysheet", 0) # 插入到最前  

>>> ws3 = wb.create_sheet("Mysheet", -1) # 插入到倒数第二
Sheets are given a name automatically when they are created. They are numbered in sequence (Sheet, Sheet1, Sheet2, …). You can change this name at any time with the Worksheet.title property:
工作表将在创建时按照数字序列自动命名（如Sheet，Sheet1，Sheet2，……）。可以在任何时候通过Worksheet.title属性修改工作表名：

>>>ws.title = "New Title"
The background color of the tab holding this title is white by default. You can change this providing an RRGGBB color code to the Worksheet.sheet_properties.tabColor attribute:
创建的工作表的标签背景色默认是白色。可以通过在Worksheet.sheet_properties.tabColor对象中设置RRGGBB格式的颜色代码进行修改：

>>>ws.sheet_properties.tabColor = "1072BA"
Once you gave a worksheet a name, you can get it as a key of the workbook:
当设置了worksheet名称，可以将名称作为工作表的索引：

>>> ws3 = wb["New Title"]
You can review the names of all worksheets of the workbook with the Workbook.sheetname attribute
可以通过Workbook.sheetname对象来查看工作簿中所有工作表的名称

>>> print(wb.sheetnames)
['Sheet2', 'New Title', 'Sheet1']
You can loop through worksheets
可以遍历整个工作簿：

>>>
