java - 无法使用 HSSF Java 删除 Excel 工作表

Question

我无法从工作簿中删除 Excel 工作表。我尝试了不同的解决方案，但无法找到解决方法。假设我想使用“wb.RemoveSheetAt(5)”删除第 5 号工作表我只能在删除第 6 个工作表后才能将其删除。

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();
