在包含自定义排序列表的列中排序数据

可能的使用场景
你可以使用自定义列表对列中的数据进行排序。这可以通过 DataSorter.addKey 方法完成。然而，此方法仅在自定义列表中的项目没有逗号时有效。如果项目中有逗号，比如 “USA,US”、“中国,CN” 等，则必须使用 **DataSorter.addKey(number, SortOrder, string[])** 方法。这里，最后一个参数不是字符串，而是字符串数组。
使用自定义排序列表对列中的数据进行排序
以下示例代码说明了如何使用 **DataSorter.addKey(number, SortOrder, string[])** 方法通过自定义排序列表对数据进行排序。请查看此代码所用的 示例Excel文件 和由其生成的 输出Excel文件。下图显示了代码执行后对样本Excel文件的效果。
