>学习笔记：
>在内存中新建一个工作薄
from openpyxl import Workbook
wb = Workbook()
保存工作薄
wb.save('test.xlsx')
#必须提交保存才能显示操作产生的效果，此操作不能在文件打开（指双击文件打开）时进行，必须先关闭。
读写已经存在的文件sheet
from openpyxl import load_workbook
wb2 = load_workbook('test.xlsx')
获取默认工作表
 ws = wb.active
 通过指定的工作表名获取工作表对象
 ws3 = wb["New Title"]
 或
 ws = wb.get_sheet_by_name('New Title')
 创建新的工作表
 ws1 = wb.create_sheet("Mysheet") 			#默认在最后面创建一个Mysheet工作表，参数也可为空，默认为sheet*
 ws2 = wb.create_sheet("Mysheet", 0) 		#在0索引位置插入一个工作表，此时插入的表名不可为空
复制工作表：
source = wb.active
target = wb.copy_worksheet(source)
删除工作表（删除后新建，相当于清空工作表）：
wb.remove(wb['Sheet'])							#wb.remove_sheet()已弃用
或del wb['Sheet']
修改工作表名称：
ws.title = "New Title"
显示所有工作表名称：
print(wb.sheetnames)
for sheet in wb:
...     print(sheet.title)
