        System.out.println("请输入乘法表：");
        for (int i = 1; i <= 9; i++) {
            int product = 0;
            for (int j = 1; j <= i; j++) {
                product = i * j;
                System.out.print(j + "*" + i + "=" + product + "\t");
            }
            System.out.println();
