Thanks guys...I was affraid of that but it doesn't make sense. If I can alter data for the cell at runtime, seems like I could alter the cell width as well.
Thanks for the quick response nevertheless.
Comment on Re^2: How to set an Excel column to 'AutoFit'
You may have misread the documentation. The "set_column" method does allow you to alter the cell width. But you have to give it a "real" width; you can't just ask for the "best fit" width (which is what AutoFit does).
I see that John has posted a link to a workaround that allows you to calculate a width that is approximately what AutoFit would give you.
