Add a colum

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,




try the maths formula node, and in the node use the ROWINDEX in the expression box.


The counter node is the most easy way here

Thank you very much Simon and Iris for your kind suggestions, the worked perfectly
