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. write_op 0x0055, [8].pack('v') end
