其中格式项都采用如下形式：
{index[,alignment][:formatString]}
其中"index"指索引占位符，这个肯定都知道；
",alignment"按字面意思显然是对齐方式,以","为标记；
":formatString"就是对输出格式的限定，以":"为标记。
alignment:可选，是一个带符号的整数，指示首选的格式化字段宽度。如果“对齐”值小于格式化字符串的长度，“对齐”会被忽略，并且使用格式化字符串的长度作为字段宽度。如果“对齐”为正数，字段的格式化数据为右对齐；如果“对齐”为负数，字段的格式化数据为左对齐。如果需要填充，则使用空白。如果指定“对齐”，就需要使用逗号。
formatString:由标准或自定义格式说明符组成。
