        text1.text = nameArray[indexPath.row] as? String
        cell.contentView.addSubview(text1)

        let text2:UILabel = UILabel.init(frame: CGRectMake(20, text1.frame.origin.y+text1.frame.size.height , 350, 30 ))
        text2.font = UIFont.systemFontOfSize(15)
        text2.text = numberArray[indexPath.row] as? String
        text2.textColor = UIColor.lightGrayColor()
        cell.contentView.addSubview(text2)


        let text3:UILabel = UILabel.init(frame: CGRectMake(0, text2.frame.origin.y+text2.frame.size.height+6 , 350, 1 ))
        text3.font = UIFont.systemFontOfSize(15)
        text3.backgroundColor = UIColor.darkGrayColor()
        cell.contentView.addSubview(text3)
