Python利用openpyxl库遍历Sheet的方法

方法一，利用 sheet.iter_rows() 获取 Sheet1 表中的所有行，然后遍历

import openpyxl
wb = openpyxl.load_workbook('example.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')
for row in sheet.iter_rows():
for cell in row:
print(cell.coordinate, cell.value)
print('--- END OF ROW ---')

sheet = wb.get_sheet_by_name('Sheet1')
for rowOfCellObjects in sheet['A1':'C3']:
for cellObj in rowOfCellObjects:
print(cellObj.coordinate, cellObj.value)
print('--- END OF ROW ---')

方法二，利用 sheet.max_row sheet.max_colum
获取 Sheet1 表中最大行和列的值，然后遍历
