How to write a specific column name in CSV.write function?

No I didn’t and I will have a look. However, I am trying to rephrase my question as follows.

I have an empty csv file named “Output”. I want to name a column as V_S1, in which S1 is a the first string element of vector List.

How can I do that rather than writing as in the comment?

using CSV, DataFrames
timeSim = 1:3;
V=[1 2 3];
List=["S1" "S2"];
#CSV.write("C:\\Users\\...\\Output.csv", DataFrame( time=timeSim, V_S1=V[:]))
CSV.write("C:\\Users\\...\\Output.csv", DataFrame( time=timeSim, println("V_$(List[1])")=V[:]))
