I'm new to Knime so sorry for maybe stupid question.
I have a problem with Insert Column Header.
I created some excel file, very simple that has few rows. I imported it to Knime and started working on it. So I tryied to extract Column header and it went great but when I want to insert it does not work. I mean I extracetd it and upper flaw is my header and bottom is content of the table. I added Insert header and conected upper line with upper and bottom with bottom, but after executed noting is happening.
So how can I add insert column header? Should I mess with flow variable in Insert mode? I tryied almost anything but no luck.
Thanks for help.
