以下是 Python 代码实现:
```python
for i in range(9, 0, -1):
for j in range(i, 0, -1):
print("{} x {} = {:2} ".format(i, j, i*j), end="")
print()
```
输出结果为:
```
9 x 9 = 81 9 x 8 = 72 9 x 7 = 63 9 x 6 = 54 9 x 5 = 45 9 x 4 = 36 9 x 3 = 27 9 x 2 = 18 9 x 1 = 9
8 x 8 = 64 8 x 7 = 56 8 x 6 = 48 8 x 5 = 40 8 x 4 = 32 8 x 3 = 24 8 x 2 = 16 8 x 1 = 8
7 x 7 = 49 7 x 6 = 42 7 x 5 = 35 7 x 4 = 28 7 x 3 = 21 7 x 2 = 14 7 x 1 = 7
6 x 6 = 36 6 x 5 = 30 6 x 4 = 24 6 x 3 = 18 6 x 2 = 12 6 x 1 = 6
5 x 5 = 25 5 x 4 = 20 5 x 3 = 15 5 x 2 = 10 5 x 1 = 5
4 x 4 = 16 4 x 3 = 12 4 x 2 = 8 4 x 1 = 4
3 x 3 = 9 3 x 2 = 6 3 x 1 = 3
2 x 2 = 4 2 x 1 = 2
1 x 1 = 1
```
