Table table = new Table(1);table.setWidth(100);
table.setTableFitsPage(true);
table.setBorderWidth(0);
table.setBorder(0);
table.getDefaultCell().setBorder(0);
table.setOffset(5);
Cell secondCell = new Cell(new Phrase("", new Font(bf2, 9)));
table.addCell(secondCell);
secondCell = new Cell(new Phrase("Global Export Control ", new Font(bf2,  9)));
secondCell.setBackgroundColor(new Color(0xC1, 0xC0, 0xC0));
secondCell.setHorizontalAlignment(Element.ALIGN_LEFT);
secondCell.setVerticalAlignment(Element.ALIGN_MIDDLE);
secondCell.setLeading(9);
table.addCell(secondCell);//Line no 1675
