如何在iTextPdf中调整PdfPCell内的PdfPTable？

我尝试使用以下代码但未成功：

    Orders listOrders = (Orders) model.get("listOrders");

    PdfContentByte pdfContentByte = writer.getDirectContent();

    Barcode128 barcode128 = new Barcode128();
    barcode128.setCodeType(Barcode128.CODE128);
    barcode128.setCode(listOrders.getGenerated_orderID());
    Image codeEANImage = barcode128.createImageWithBarcode(pdfContentByte, null, null);
    codeEANImage.scalePercent(100);

    Font font = FontFactory.getFont(FontFactory.HELVETICA);
    font.setColor(BaseColor.BLACK);
    font.setSize(8);

    Image image = Image.getInstance(logo);

    Paragraph paragraph = new Paragraph("some text",font);
    paragraph.setAlignment(ALIGN_CENTER);
    document.add(paragraph);

    PdfPTable table = new PdfPTable(3);
    table.setWidthPercentage(80);
    table.setWidths(new int[]{1, 1, 1});

    PdfPCell pdfPCell = new PdfPCell();
    pdfPCell.setImage(image);

    image.scalePercent(10);
    table.addCell(pdfPCell);


    table.addCell(codeEANImage);
    table.addCell(listOrders.getSender_address());

    PdfPTable tableLeft = new PdfPTable(2);
    tableLeft.setWidthPercentage(40);
    tableLeft.setWidths(new int[]{1, 1});
    tableLeft.getDefaultCell().setBorder(Rectangle.NO_BORDER);

    PdfPCell leftLabel = new PdfPCell(new Phrase("Sender",font));
    leftLabel.setColspan(2);

    tableLeft.addCell(leftLabel);

    tableLeft.addCell(new Phrase("Person:",font));
    tableLeft.addCell(new PdfPCell(new Phrase(listOrders.getPersonality(),font))).setBorder(Rectangle.BOX);

    PdfPTable tableRight = new PdfPTable(2);
    tableRight.setWidthPercentage(40);
    tableRight.setWidths(new int[]{1, 1});
    tableRight.getDefaultCell().setBorder(Rectangle.NO_BORDER);

    PdfPCell rightLabel = new PdfPCell(new Phrase("Rec:",font));
    rightLabel.setColspan(2);

    tableRight.addCell(rightLabel);

    tableRight.addCell(new Phrase("Name:",font));
    tableRight.addCell(new PdfPCell(new Phrase(listOrders.getReceiver_firstname(),font))).setBorder(Rectangle.BOX);

    table.addCell(tableLeft);
    table.addCell(tableRight);
    table.setSpacingBefore(0);

    document.add(table);

有人可以建议我如何构建它吗？
