九九乘法表
1 * 1 = 1
1 * 2 = 2	2 * 2 = 4
1 * 3 = 3	2 * 3 = 6	3 * 3 = 9
1 * 4 = 4	2 * 4 = 8	3 * 4 = 12	4 * 4 = 16
1 * 5 = 5	2 * 5 = 10	3 * 5 = 15	4 * 5 = 20	5 * 5 = 25
1 * 6 = 6	2 * 6 = 12	3 * 6 = 18	4 * 6 = 24	5 * 6 = 30	6 * 6 = 36
1 * 7 = 7	2 * 7 = 14	3 * 7 = 21	4 * 7 = 28	5 * 7 = 35	6 * 7 = 42	7 * 7 = 49
1 * 8 = 8	2 * 8 = 16	3 * 8 = 24	4 * 8 = 32	5 * 8 = 40	6 * 8 = 48	7 * 8 = 56	8 * 8 = 64
1 * 9 = 9	2 * 9 = 18	3 * 9 = 27	4 * 9 = 36	5 * 9 = 45	6 * 9 = 54	7 * 9 = 63	8 * 9 = 72	9 * 9 = 81

代码：

public class Demo {
    public static void main(String[] args) {
        // 定义起始行
        int row = 1;
        // 最大打印 9 行
        while (row <= 9) {

            // 定义起始列
            int col = 1;
            // 最大打印 row 列
            while (col <= row) {
                System.out.printf("%d * %d = %d\t", col, row, row * col);
                //列数 + 1
                col += 1;
            }
            //一行打印完成的换行
            System.out.println("");
            // 行数 + 1
            row += 1;
        }
    }
}
