无法使用HSSF Java删除Excel工作表

Question

我无法从工作簿中删除excel表。我尝试了不同的解决方案，但我无法得到解决方法。假设我想使用“wb.RemoveSheetAt（5）”删除第5页。我只能在删除第6页后删除它。

代码：

public void cloneSheet(String sheetName , int NoOfClones){
    int temp = 0;
    for(int i = 0 ; i <= NoOfClones ; i++){
        HSSFSheet tsheet = workbook.cloneSheet(temp = workbook.getSheetIndex(sheetName));
        workbook.setSheetName((workbook.getSheetIndex(tsheet)), sheetName+i);   
    }
    workbook.removeSheetAt(workbook.getSheetIndex(sheetName));
}

这是我得到的错误：

Answer 1

FileInputStream fileStream = new FileInputStream(excelFile);
POIFSFileSystem poiFS = new POIFSFileSystem(fileStream);
HSSFWorkbook workbook = new HSSFWorkbook(poiFS);
workbook.removeSheetAt(5);
FileOutputStream output = new FileOutputStream(excelFile);
workbook.write(output);
output.close();
