JLabel添加新线

Question

所以我试图在我的JLabel上添加一个新行来显示所有的汽车贷款摊销时间表，由于某种原因，“\ n”不起作用。 这是代码：

for (int i = 1; i <= newYears; i++) {
            interest = newRate2 * amount;
            principal = monthlyPayment - interest;
            amount = amount - principal;
            //console
            System.out.println(i + "\t\t" + df.format(principal) + "\t\t" + df.format(interest) + "\t\t" + df.format(amount));
            //Second Frame where i want to show the full amortization schedule
            second.jlsPayment2.setText("" + i + "                                " + df.format(principal) + "                     " + df.format(interest) + "                        \n" + df.format(amount));
        }

非常感谢任何帮助，谢谢
