I try to master the Talend data preparation software .
Is it possible to edit cells by :
- By simply writing within ?
- Summing two columns ? (I can concatenate, but i also would like to sum the values wich are inside the columns)
- Making other kind of operations ?
If it's possible, I don't know how to do it with the functions
When I permute two columns, this change is not added to the recipe, isn't it ?
What are the software limits?
Thank you for your attention.
