Fitting a JTable in an iText PDF Document

I have a

that has four columns. I am using iText libraries to print PDF documents with data from the JTable. The problem is that the JTable is not showing properly in the PDF. I have searched on Google and came across the same situation here. The code is similar to mine as well as the output. I have also tried this example using Templates, however, the result is not changing.

How do we solve this? Please assist. If the codes are necessary, i will post but they are too many classes -i am working on a big application. The concept I would want is to make the JTable fit on the document.

After a long struggle, I managed to make it as shown below. In case someone encounters this, here is the idea that saved me:

public void actionPerformed(ActionEvent e) {

        try {
            Document doc = new Document();
            PdfWriter.getInstance(doc, new FileOutputStream("table.pdf"));
            PdfPTable pdfTable = new PdfPTable(table.getColumnCount());
            //adding table headers
            for (int i = 0; i < table.getColumnCount(); i++) {
            //extracting data from the JTable and inserting it to PdfPTable
            for (int rows = 0; rows < table.getRowCount() - 1; rows++) {
                for (int cols = 0; cols < table.getColumnCount(); cols++) {
                    pdfTable.addCell(table.getModel().getValueAt(rows, cols).toString());

        } catch (DocumentException ex) {
            Logger.getLogger(MainWindow.class.getName()).log(Level.SEVERE, null, ex);
        } catch (FileNotFoundException ex) {
            Logger.getLogger(MainWindow.class.getName()).log(Level.SEVERE, null, ex);
