提前自定义path和filename
writer = pd.ExcelWriter(path+filename+'.xlsx')
total_head.to_excel(writer,sheet_name = 'sheet1',index = False)
heads.to_excel(writer,sheet_name = 'sheet1',index = True,header = False,startrow = 14)
pure_data.to_excel(writer,sheet_name = 'sheet1',index = False,header = False,startrow = 19,startcol = 1)
writer.save()
