将表数据旋转90度(2007-11-19于海南三亚)

将下表数据：
A                    b           c           d           e           
-------------------- ----------- ----------- ----------- ----------- 
x                    1           2           3           4
y                    5           6           7           8
z                    9           10          11          12

转化成如下结果：
a                    x          y          z          
-------------------- ---------- ---------- ---------- 
b                    1          5          9

d                    3          7          11
e                    4          8          12
