df.columns.tolist()下面是异常堆栈跟踪，
InputStream isXls = new FileInputStream("machine_operator_report.xls");
HSSFWorkbook workbookOld = new HSSFWorkbook(isXls);
我已经尝试过堆栈中提供的所有解决方案以进行转换
Exception in thread "main"
org.apache.poi.hssf.record.RecordFormatException: WINDOW2 was not found

到HSSFWorkbook，但是执行代码时出现上述异常。我要转换为XSSFWorkbook的{{1}}也包含图。
如果您能为此提供帮助，它将对我有很大帮助！！谢谢
