		}
	}
	
	public static PdfPTable createTab(){
		PdfPTable table = new PdfPTable(6);
		try {
			table.setLockedWidth(true);
			table.setTotalWidth(505);
			//table.setWidthPercentage(100);
			int rw = 505/6;
			table.setWidths(new int[]{rw,rw,rw,rw,rw,rw});
			for (int i = 0;i<6*5;i++) {
				table.addCell(new Paragraph(i+"-"));
