即使使用下面的代码，.xlsx 文件每张纸上的内容也会被覆盖，而不是附加。缺什么？

writer = pd.ExcelWriter(excelfilepath, engine='openpyxl', mode='a', if_sheet_exists='overlay')\n\ndf1.to_excel(writer, sheet_name='N\xc3\xbacleo de TRIAGEM')\n\ndf2.to_excel(writer, sheet_name='N\xc3\xbacleo de FAL\xc3\x8aNCIAS')\n\ndf3.to_excel(writer, sheet_name='RE - Triagem')\n\ndf4.to_excel(writer, sheet_name='RE - Fal\xc3\xaancias')\n\nwriter.save()\n
