for i in range(1, 10):
    for j in range(1, i + 1):
        print(j, '*', i, '=', i * j, end="  ")  #end= 以。。。结尾
    print()

运行结果：

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

 

发现乘法表有错位，在程序中加入制表符，就解决了

程序如下：

for i in range(1, 10):
    for j in range(1, i + 1):
        print(j, '*', i, '=', i * j, end="\t")
    print()

运行结果：
