Dear KNIME community members, I am a newbie to KNIME, which I find very interesting for my cheminformatics work. I am designing my first workflow, and I am having a hard time to get a new column inserted in a table, and afterwards add the row number into each cell of the new column. I would greatly appreciate if anyone can point me out which would be the most effcicient way to getmthis,

Thank you very much in advance,

Regards

Alfredo
