P.S.:Thats part of my code:

private static PdfPTable createFirstTable() throws DocumentException, IOException {
    PdfPTable table = new PdfPTable(13);

     BaseFont baseFont = BaseFont.createFont("times.ttf", BaseFont.IDENTITY_H, true);
     Font deckFont = new Font(baseFont, 12f);
     deckFont.setColor(BaseColor.RED); 
     table.getDefaultCell().setHorizontalAlignment(Element.ALIGN_CENTER);
     table.getDefaultCell().setVerticalAlignment(Element.ALIGN_MIDDLE);
     table.getDefaultCell().setPaddingBottom(15);
     table.getDefaultCell().setPaddingTop(15);

     Font deckFont1 = new Font(baseFont, 12f);
     deckFont1.setColor(BaseColor.BLACK); 
    for (int i = 0; i < 4; i++) {
        switch (i) {
        case 0:

            for (int j = 0; j < 13; j++) {
