ArrayList和itextpdf，表

Question

我有30行的表和数组列表中的字符串。表有2列，第一列是公司名称，第二列我需要从列表中编写字符串，第二列的每一行应该有10个元素，如何我这样做了吗？

PDF输出应该是这样的：

Company name |||| DESTINATION      
AirFrance |||| Tokio,London,Istanbul,New Nork,Paris,Vienna,OSLO,Belgrade,Budapest,Amsterdam.

每家公司都应从列表中读取10个目的地。

这可能很容易，我只能看到我试图计算列表元素并以某种方式对其进行分区，但它没有用。

顺便说一下，我使用itextpdf库，然后从excel中读取这些数据。

这是代码：

public class ReadExcel {
    private String inputfile;
    private List<Avio> avioni;

    public ReadExcel() {

        this.avioni = new ArrayList<Avio>();
    }


public List<Avio> getAvioni() {
    return avioni;
}

public void setAvioni(List<Avio> avioni) {
    this.avioni = avioni;
}

public String getInputfile() {
    return inputfile;
}

public void setInputfile(String inputfile) {
    this.inputfile = inputfile;
}

public void citaj(String naziv) {
    Avio a = new Avio();

    try {
        Workbook w = Workbook.getWorkbook(new File(naziv));
        Sheet sheet = w.getSheet(0);
        // System.out.println(sheet.getRows());
        for (int i = 1; i < sheet.getRows(); i++) {
            Avio tmpAvio = new Avio();

            tmpAvio.setDrzava(sheet.getCell(0, i).getContents());
            System.out.println();
            tmpAvio.setNazivKomp(sheet.getCell(1, i).getContents());
            tmpAvio.setVlasnik(sheet.getCell(2, i).getContents());
            tmpAvio.setBrAviona(Integer.parseInt(sheet.getCell(3, i)
                    .getContents()));
            tmpAvio.setGod(Integer.parseInt(sheet.getCell(4, i)
                    .getContents()));

            tmpAvio.setDatum(sheet.getCell(6,i).getContents());
            tmpAvio.setModelAviona(sheet.getCell(7,i).getContents());
            tmpAvio.setKapetan(sheet.getCell(8,i).getContents());
            tmpAvio.setJMBG(sheet.getCell(9,i).getContents());
            tmpAvio.setIskustvo(sheet.getCell(10,i).getContents());
            tmpAvio.setBrPutnika(sheet.getCell(11,i).getContents());
            tmpAvio.setLet(sheet.getCell(12,i).getContents());

            avioni.add(tmpAvio);


        }

        Sheet sheet1 = w.getSheet(1);

        List<String> destinacije = new ArrayList<String>();
        for (int i = 0; i < sheet1.getRows(); i++) {
            for (int j = 0; j < sheet1.getColumns(); j++) {

                destinacije.add(sheet1.getCell(j, i).getContents());
                System.out.println(sheet1.getCell(j,i).getContents()+i+","+j);
            }
            avioni.get(i).setDestinacije(destinacije);
            System.out.println(avioni.get(i));
        }


    }

    catch (BiffException e1) {

        e1.printStackTrace();
    } catch (IOException e) {
