Set the width (in units of 1/256th of a character width)

如果你看HSSFSheet.setColumnWidth()方法的Javadoc，它有字符宽度的解释。粘贴以下摘录:

Character width is defined as the maximum digit width of the numbers 0, 1, 2, ... 9 as rendered using the default font (first font in the workbook). Unless you are using a very special font, the default character is '0' (zero), this is true for Arial (default font font in HSSF) and Calibri (default font in XSSF)
