How to add a new column side by side in KNIME? Like If we create a new column by any aggregation method or any calculation method, the new column will add at the end. How can we create a new column beside the column which we used as an aggregated column?
As far as I know, this is not possible.
However, you can use the Table Manipulation or Column Resorter nodes to alter the column order.
Hi @Bijal
I might be missing the point so I’m wondering if it wouldn’t help to provide and example to better understand what you want to achieve. Could you please provide a simple example here with a table with columns and then the result with the “added column” containing the “aggregated values” ? It would help a lot.
Thanks & regards,

Hi @aworker,
For example, I have a column A, B, C, D, E. If I add a new column X( Suppose X new column is created with the help of column A, B. suppose a new column created by column A + Column B).
By doing this newly created column will be added at the end like this A, B, C, D, X
But I need the order like this-> A, B, X, C, D
Suppose again I am creating a new column Y(Y = Column D + E) then Column Y will be added at the end.
I need a column order as this: A, B, X, C, D, Y( Newly created column should be beside the depended column not at the end. I need columns in this order.)
Hi @Bijal
Thanks for your quick answer with explanations. There is a specific node to achieve column aggregation:
One can choose what columns to aggregate in several different ways. Then, one needs to use the Column Resorter node:
These two nodes should do the trick (as already mentioned by @elsamuel). You would need to know what is the final order of your columns in advance to set it as you want it to be, i.e. A B X C D Y, as in your example.
Would this be a good enough solution to your problem ?
Hope this helps.
Best
