Thanks for trying.
But its not what I am looking for.. though its correct for my example below its not correct for the whole data I have.
Let me re-define the data rows for a better view
Index Name Value
1 A 1.0 x
1 A 2.0 x
1 B 1.0
1 B 2.0
2 A 4.0 x
2 A 5.0 x
3 B 6.0 x
3 B 7.0 x
3 C 6.0
3 C 7.0
Whatever...
