Build 2.5.0.104 of xlsgen improves the way auto-fit is processed.

Before that build, if you tried to auto-fit column A with a statement like this :

worksheet.Columns("A2:A5").AutoFit = True

xlsgen would compute the auto-fit on column A by computing the size of everything in that column, not just the content of rows 2 to 5.

Now those rows are taken care of, and can be used to limit the rows to process in that column.

It's still possible of course to apply auto-fit to the entire column, with a statement like this :

worksheet.Columns("A:A").AutoFit = True
