How to read empty cells of an excel file using POI

I have tried to read an excel file using POI and then I wanted to put that data into a JTable.

Here is the excel file,

As you can see, there are two empty cells in the above table, once I read above data into a JTable I got following result,

In my JTable, empty cells has moved to a wrong place, I used following codes to get this result please assist me to achieve the correct result,

private XLSContainer xLSContainer;
    Vector cellVectorHolder;
    private int noOfCells=0;

    public XLSContainer readXLS(XLSFile xLSFile) {
        cellVectorHolder = new Vector();

        try {

            FileInputStream inputStream = new FileInputStream(xLSFile.getFileName());

            POIFSFileSystem pOIFSFileSystem = new POIFSFileSystem(inputStream);

            HSSFWorkbook hSSFWorkbook = new HSSFWorkbook(pOIFSFileSystem);

            HSSFSheet hSSFSheet = hSSFWorkbook.getSheetAt(0);

            Iterator rowIter = hSSFSheet.rowIterator();


            while (rowIter.hasNext()) {
                HSSFRow row = (HSSFRow) rowIter.next();
                if(row.getRowNum()==0){
                    noOfCells = row.getLastCellNum();
                }
                Iterator cellIter = row.cellIterator();

                Vector cellStoreVector = new Vector();

                while (cellIter.hasNext()) {
                    HSSFCell hSSFCell = (HSSFCell) cellIter.next();
                    //System.out.println(hSSFCell.getCellNum());
                    cellStoreVector.addElement(hSSFCell);
                }
                cellVectorHolder.addElement(cellStoreVector);

            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        feedXLSContainer();
        return xLSContainer;
    }//
