Itext - pdf uso di PdfTable

[assmazz]

Non riesco ad ottenere in con il pdf la seguente forma tabellare:

<table width="620" border="1">   <tr>     <td width="20" rowspan="2" colspan=2></td>      <td width="11" colspan=2 rowspan="1"></td>     <td width="11" colspan=4 rowspan="1"></td>     <td width="11" colspan=3 rowspan="1"></td>        </tr>   <tr>          <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>   </tr>   <tr>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>     <td></td>   </tr> </table> 

qui il mio codice

public static PdfPTable createFirstTable() {

         PdfPTable table = new PdfPTable(11);
        PdfPCell cell1 = GetCell("territorio",2,2);
        table.addCell(cell1);
        table.addCell(GetCell("A",2,1));
        table.addCell(GetCell("B",4,1));
        table.addCell(GetCell("C",3,1));
 
        table.addCell(GetCell("D"));
        table.addCell(GetCell("E"));
        table.addCell(GetCell("F"));
        table.addCell(GetCell("G"));
        table.addCell(GetCell("H"));
        table.addCell(GetCell("I"));
        table.addCell(GetCell("L"));
        table.addCell(GetCell("M"));
        table.addCell(GetCell("N"));
        
        table.addCell(GetCell("1"));
        table.addCell(GetCell("2"));
        table.addCell(GetCell("3"));
        table.addCell(GetCell("4"));
        table.addCell(GetCell("5"));
        table.addCell(GetCell("6"));
        table.addCell(GetCell("7"));
        table.addCell(GetCell("8"));
        table.addCell(GetCell("9"));
        table.addCell(GetCell("10"));
        table.addCell(GetCell("11"));
        return table;
    }
    
    private static PdfPCell GetCell(String text) {
        return GetCell(text, 1, 1);
    }
    private static PdfPCell GetCell(String text, int colSpan, int rowSpan ) {
        PdfPCell cell = new PdfPCell(new Phrase(text));
        cell.setHorizontalAlignment(1);
        cell.setRowspan(rowSpan);
        cell.setColspan(colSpan);
        
        return cell;
    }
