Hi,
I would like to convert all the columns in my table into rows grouped by my id column. Say for example I have the following table:
ID | a1 | a2 |
1 | 2 | 4 |
2 | 4 | 6 |
3 | 3 | 5 |
I need to convert it into the following table
ID | a | value |
1 | 1 | 2 |
1 | 2 | 4 |
2 | 1 | 4 |
2 | 2 | 6 |
3 | 1 | 3 |
3 | 2 | 5 |
Is there any way I can do this in Knime. I tried the Pivot node but with no success.
Your help is much appreciated!
Thanks,
