I am trying to hide some columns from a CSV file starting at specifiedc column index using the following code:
FileStream fstream = new FileStream(myPath, FileMode.Open);
LoadOptions lo = new LoadOptions(LoadFormat.CSV);
Workbook wk = new Workbook(fstream,lo);
Worksheet ws = wk.Worksheets;
The code runs with no problem but when I open the file the columns are not hidden. I am attaching the file I am using.. can you please advise?
Thank you much
