16 ws1.title="range names"
17 for i in range(1,10):
18     for j in range(1,5):
19         ws1.cell(i,j)
20         print(get_column_letter(j))

23 ws3=wb.create_sheet("data")
24 for row in range(10,20):

27 wb.save(filename=new_filename)

读取一个存在的工作簿

>>> from openpyxl import load_workbook
>>> wb = load_workbook(filename = 'empty_book.xlsx')
>>> sheet_ranges = wb['range names']
>>> print(sheet_ranges['D18'].value)
