我有一个数据表，不幸的是我有两个标题行：
Measures Product 4Weeks10-19-14 4Weeks10-19-14 Week09-28-14 Week09-28-14
Measures Product Current Change vs YA Current Change vs YA
Avg Units Apples 22.93 -1.68 22.30 -2.96
Avg Units Oranges 3.68 0.76 3.00 -0.13
Avg Units Plums 13.93 0.87 13.66 -0.27
Avg Units Pineapples 2.49 -0.66 2.48 -0.65
Avg Units Hot Pockets 28.59 1.05 28.80 0.29
我想将第一个标题行转到一个列，如下所示：
Measure Product Time Current Change vs YA
Avg Units Apples 4Weeks10-19-14 22.93 -1.68
Avg Units Oranges 4Weeks10-19-14 3.68 0.76
Avg Units Plums 4Weeks10-19-14 13.93 0.87
Avg Units Pineapples 4Weeks10-19-14 2.49 -0.66
Avg Units Hot Pockets 4Weeks10-19-14 28.59 1.05
Avg Units Apples Week09-28-14 22.30 -2.96
Avg Units Oranges Week09-28-14 3.00 -0.13
Avg Units Plums Week09-28-14 13.66 -0.27
Avg Units Pineapples Week09-28-14 2.48 -0.65
Avg Units Hot Pockets Week09-28-14 28.80 0.29
我过去曾使用过UNPIVOT（对不起，只有一次），但我不知道如何处理这个问题。
提前感谢您的帮助！
