该方法是不言自明的并评论:

private void sheetAutoFitColumns(WritableSheet sheet) {
    for (int i = 0; i < sheet.getColumns(); i++) {
        Cell[] cells = sheet.getColumn(i);
        int longestStrLen = -1;

        if (cells.length == 0)
            continue;

        /* Find the widest cell in the column. */
        for (int j = 0; j < cells.length; j++) {
            if ( cells[j].getContents().length() > longestStrLen ) {
                String str = cells[j].getContents();
                if (str == null || str.isEmpty())
                    continue;
                longestStrLen = str.trim().length();
            }
        }

        /* If not found, skip the column. */
        if (longestStrLen == -1) 
            continue;

        /* If wider than the max width, crop width */
        if (longestStrLen > 255)
            longestStrLen = 255;

        CellView cv = sheet.getColumnView(i);
        cv.setSize(longestStrLen * 256 + 100); /* Every character is 256 units wide, so scale it. */
        sheet.setColumnView(i, cv);
    }
}
