python如何将九九乘法表写入到Excel？

import xlwings as xw

import os

curpath=os.path.dirname(__file__)

filename=os.path.join(curpath,'example_99.xlsm')

@xw.sub

def py_99():

wb = xw.Book.caller()

wt = wb.sheets[0]

for i in range(1,10):

for j in range(1,10):

if i>=j:

wt.range(i+10,j).value=str(i)+'*'+str(j)+'='+str(i*j)

if __name__ == "__main__":

xw.Book(filename).set_mock_caller()

py_99()
