Column widths change with each new import from Access 2007

I am using an invoice template I designed that pulls records from an Access
2007 query. The number of records imported changes each time the template is
used for a new workbook. I've managed at last to get the results I want from
the import, but the column widths for the data changes each time to widths
other than what I'd saved them as. It is totally screwing up the formatting I
want for the worksheet. How can I lock the widths of these columns at what I
want them, regardless of what data is imported?
