 - 增强了excel格式。可以比较简洁地excel配置**任意复杂**的数据，像子结构、结构列表，以及更复杂的深层次的嵌套结构都能直接解析处理。
 - 完备的类型系统和多原始数据支持（xml、json、lua、yaml），可以轻松表达和解析**任意复杂**的数据。意味着传统excel导表工具无法处理的技能、行为树、副本等等复杂配置，luban也能够统一处理了，彻底将程序从复杂的配置解析中解放出来。
 - 完善的工作流支持。如id的外键引用检查;资源合法性检查;灵活的数据源定义（拆表或者多表合一）;灵活的分组导出机制；多种本地化支持;生成极快（日常迭代300ms以内）；Excel2TextDiff工具方便diff查看excel文件的版本间差异；
-- **=== LubanAssistant Excel插件 ===**。支持把json、lua、xml等文本格式的配置数据加载到excel中，批量编辑处理，最后再保存回原文件，较好地解决大型项目中多人合作数据编辑冲突合并的问题，较好解决在编辑器中制作的配置难以在excel中批量修改的问题。

 ## 特性
 - 支持excel族、json、xml、lua、yaml 多种数据格式，基本统一了游戏常见的配置数据
 - **强大完备的类型系统**。**可以优雅表达任意复杂的数据结构**。支持所有常见原生类型、datetime类型、容器类型list,set,map、枚举和结构、**多态结构**以及**可空类型**。
-- 支持增强的excel格式。可以在excel里比较简洁填写出非常复杂的数据（比如顶层字段包含"list,A"类型字段， 而A是结构并且其中又包含"list,B"类型字段，B也是结构并且包含"list,C"这样的字段...）。
-- 生成代码清晰易读、良好模块化。特地支持运行时原子性热更新配置。
-- 生成极快。支持常规的本地缓存增量生成模式，也支持云生成模式。MMORPG这样大型项目也能秒内生成。日常增量生成基本在300ms以内，项目后期极大节省了迭代时间。另外支持**watch监测模式**，数据目录变化立即重新生成。

 ## 增强的excel格式
 luban支持在excel中解析任意复杂的数据结构，哪怕复杂如技能、行为树（但在实践中一般使用编辑器制作这些数据，以json格式保存，而不会在excel里填写）。下面从简单到复杂展示在luban中配置这些数据的方式。
