    #      0     2  Column width in characters, using the width of the zero
    #               character from default font (first FONT record in the
    #               file). Excel adds some extra space to the default width,
    #               depending on the default font and default font size. The
    #               algorithm how to exactly calculate the resulting column
    #               width is not known.
    #
    #               Example: The default width of 8 set in this record results
    #               in a column width of 8.43 using Arial font with a size of
    #               10 points.
