本篇文章讲解openpyxl在sheet底部追加一行数据、在指定位置插入一行

　　1、openpyxl追加一行

　　append()方法，是在sheet中追加一行数据,参数可以使列表、元祖、range对象、字典、生成器，源码如下：

   def append(self, iterable):

　　"""Appends a group of values at the bottom of the current sheet.

　　* If it's a list: all values are added in order, starting from the first column

　　* If it's a dict: values are assigned to the columns indicated by the keys (numbers or letters)

　　:param iterable: list, range or generator, or dict containing values to append

　　:type iterable: list|tuple|range|generator or dict

# -*- 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)

# 追加一行
for sheet in wb:
    sheet.append(['name','name2'])

# 在A列和B列追加(参数为字典)
for sheet in wb:
    sheet.append({'A':'dicta','B':'dictb'})

wb.save('test.xlsx')

　　2、openpyxl插入一行或多行(插入的是空行)，官方文档如下：

　　You can insert rows or columns using the relevant worksheet methods:
　　openpyxl.worksheet.worksheet.Worksheet.insert_rows()
　　The default is one row or column. For example to insert a row at 7 (before the existing row 7):

　　ws.insert_rows(7) # 在第7行前面插入一行

# -*- 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)

# 追加一行
for sheet in wb:
    sheet.append(['name'])
    
# 第一行插入空行
for sheet in wb:
    sheet.insert_rows(1)
    
# 在第2行往下数3行插入空行(2、3、4行)
for sheet in wb:
    sheet.insert_rows(2,3)

wb.save('test.xlsx')
