方法名：length

StringUtils.length介绍

[英]Gets a CharSequence length or 0 if the CharSequence is null.
[中]获取CharSequence长度，如果CharSequence为null，则获取0。

private String getDataFormat(ColumnDefine columnDefine, int width, String data) {
  switch (columnDefine.align) {
    case MIDDLE: {
      final int length = StringUtils.length(data);
      final int diff = width - length;
      final int left = diff / 2;
      return repeat(" ", diff - left) + "%s" + repeat(" ", left);
    }
    case RIGHT: {
      return "%" + width + "s";
    }
    case LEFT:
    default: {
      return "%-" + width + "s";
    }
  }
}

/**
 * 获取一个字符串的可视宽度<br/>
 * 什么叫一个字符串的可视宽度呢？很简单，因为字符串有换行行为，所以一个字符串的宽度不能简单的根据字符串的长度来判断<br/>
 * 例如："abc\n1234"，这个字符串的可视宽度为4
 *
 * @param string 字符串
 * @return 字符串可视宽度
 */
private static int width(String string) {
  int maxWidth = 0;
  final Scanner scanner = new Scanner(new StringReader(string));

      maxWidth = max(length(scanner.nextLine()), maxWidth);
    }
  } finally {
    scanner.close();
  }
