Table table = new Table(new float[2]);

Cell cell=new Cell().setWidth(70).setBorder(Border.NO_BORDER).setHorizontalAlignment(HorizontalAlignment.RIGHT).add(new Paragraph(entry.getKey()).setFont(sysFont).setFontSize(10));
Cell cell1=new Cell().setBorder(Border.NO_BORDER).setHorizontalAlignment(HorizontalAlignment.LEFT).add(new Paragraph(entry.getValue()).setFont(sysFont).setFontSize(10));
