Aha, Indeed I was not aware that the vector behaves similar to a quoted list (although I could have implied that from the behavior). So thank you very much for showing me the right way.

[] quotes whatever you feed it, so that's not a list with a string, a
number and nil, but a string, a symbol, and nil.
You probably want
`[("Col1" ,col1-width nil)
("Col2" ,col2-width nil)]
or use the functions `vector' and `list' instead of literals.
