使用for的嵌套循环，打印九九乘法表

当然可以。使用嵌套的`for`循环来打印九九乘法表是一种常见的编程练习。这是一个简单的例子，展示了如何用Python编写：

for i in range(1, 10):  # 外层循环，控制行数（从1到9）
    for j in range(1, i+1):  # 内层循环，控制列数（从1到当前行数）
        print(f"{j} * {i} = {i*j}", end="\t")  # 打印每个乘积，并用制表符分隔
    print()  # 每一行结束后换行

运行上述代码，你会得到如下的九九乘法表：

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
