让格式弄成这样：

9*9=81  9*8=72  9*7=63  9*6=54  9*5=45  9*4=36  9*3=27  9*2=18  9*1=9   
        8*8=64  8*7=56  8*6=48  8*5=40  8*4=32  8*3=24  8*2=16  8*1=8   
                7*7=49  7*6=42  7*5=35  7*4=28  7*3=21  7*2=14  7*1=7   
                        6*6=36  6*5=30  6*4=24  6*3=18  6*2=12  6*1=6   
                                5*5=25  5*4=20  5*3=15  5*2=10  5*1=5   
                                        4*4=16  4*3=12  4*2=8   4*1=4   
                                                3*3=9   3*2=6   3*1=3   
                                                        2*2=4   2*1=2   
                                                                1*1=1  
需要考虑什么问题？
