This is not an issue for me necessarily , just letting you guys know in Worksheet.php right where you begin the sheet (in startSheet()) you can define column widths.

I ended up just prepending the following string to give columns 1 (min) through 7 (max) columns (A:G) with the specified parameters, right before the tag.

Great library, Really prefer it to some of the memory intensive alternatives. If no one has time I can do it myself, but not immediately as I've got a bunch of work to catch up with at the moment. Thanks for your great work. Really came in handy.
