I am new here. I need your advice so much
I need to sum up each columns
To understand the node, I made it , but I don’t know how to make it through Loop
If I use the math formula, only one column is added up. I want to know how to use N
For example, Column1+10 = new Column1, Column2+11 =new Column2 …
ColumnN+N+9 = new ColumnN
Please advise how to do it.
Thank you in advance for your help.
Hello @onetonic33 and welcome to the KNIME forum
The specific nodes that allows you to loop through columns are ‘Column List Loop Start’ and ‘Loop End (Column Append)’
I hope this is helping you.
to my knowledge there is no simple solution to this kind of column manipulation (simple meaning using function in Math Formula Multi Column node). For ideas check this topic:
Additionally I have created a workflow example which might do what you need. Take a look and if any questions feel free to ask.
