Using xlsxwriter to Align Left a Row

Question

xlsxwriter has been pretty powerful and almost everything I want is working, but the following attempt to align left a single row doesn't seem to work.

stats = DataFrame(...)
xl_writer = ExcelWriter(r'U:\temp\test.xlsx')
stats.to_excel(xl_writer, 'Stats')

workbook = xl_writer.book
format_header = workbook.add_format({'align': 'left'})
stats_sheet = xl_writer.sheets['Stats']
stats_sheet.set_row(0, None, format_header)
