Question

最初我使用了4行数据然后我删除了最后两行。问题是，我仍然得到4作为总行数。我该怎么做以获得更新计数。

    FileInputStream inputStream = new FileInputStream(new File(excelFilePath));

    Workbook workbook = new XSSFWorkbook(inputStream);
    Sheet firstSheet = (Sheet) workbook.getSheetAt(0);
    System.out.println("No of rows:"+firstSheet.getPhysicalNumberOfRows());
    Iterator<Row> iterator = firstSheet.iterator();

    try{

    while (iterator.hasNext()) {
        Row nextRow = iterator.next();
        Iterator<Cell> cellIterator = nextRow.cellIterator();                      

        while (cellIterator.hasNext()) {

            Cell cell = cellIterator.next();
            cell.setCellType(Cell.CELL_TYPE_STRING);

             if(!cell.getStringCellValue().isEmpty()){

                 switch (cell.getCellType()) {
                 case Cell.CELL_TYPE_STRING:
                     writer.append(cell.getStringCellValue());                         
                     break;                   

             }
             }             
             }               
             }       
      }finally{
        inputStream.close();
        workbook.close();           
        writer.flush();
        writer.close();            

    }

通过删除Excel中的整行来清除该问题。如果要删除Excel中的某些数据，请不要清除单元格中的内容而是删除整行。
