万事万物的操作都是增删改查，sheet也不例外，前面我们讲了openpyxl查询和增加sheet的操作，本节课说下修改和删除的操作。

　　1、修改sheet名字(通过sheet对象的title属性)

　　You can change this name at any time with theWorksheet.title property:

	　　ws.title = "New Title"

　　2、修改sheet名背景颜色(通过sheet对象的sheet_properties.tabColor属性)

　　The background color of the tab holding this title is white by default. You can change this providing anRRGGBBcolor code to theWorksheet.sheet_properties.tabColor attribute:

	　　ws.sheet_properties.tabColor = "1072BA"

　　3、删除sheet(通过remove方法)

	　　wb.remove(sheet) #参数为sheet对象而非sheet名

　　1、修改sheet名代码如下：

# -*- coding: utf-8 -*-
from openpyxl import Workbook

wb = Workbook() # 默认生成一个名为Sheet的sheet

# 创建sheet
for name in ['a','b']:
    wb.create_sheet(name)

# 修改sheet名字
num = 1
for sheet in wb:
    name = sheet.title + str(num)
    sheet.title = name

# 获取sheet名
sheet_names = wb.sheetnames
print(sheet_names)

wb.save('test.xlsx')

D:python3installpython.exe D:/pyscript/py3script/python66/test2/test.py
['Sheet1', 'a1', 'b1']

Process finished with exit code 0

　　2、修改sheet名文背景色代码如下

# -*- coding: utf-8 -*-
from openpyxl import Workbook

wb = Workbook() # 默认生成一个名为Sheet的sheet

# 创建sheet
for name in ['a','b']:
    ws = wb.create_sheet(name)

# 修改sheet名背景色
for sheet in wb:
    sheet.sheet_properties.tabColor = '1072BA'

wb.save('test.xlsx')

　　3、删除sheet

# -*- coding: utf-8 -*-
from openpyxl import Workbook

wb = Workbook() # 默认生成一个名为Sheet的sheet

# 创建sheet
for name in ['a','b']:
    ws = wb.create_sheet(name)

# 删除sheet
ws = wb['a']
wb.remove(ws)

wb.save('test.xlsx')
