Steps To Reproduce

[ [ "是否有宣传工作总负责人*" ], [ "有，总负责人信息", "姓名*" ], [ "有，总负责人信息", "职务*" ], [ "有，总负责人信息", "级别*" ], [ "有，总负责人信息", "联系电话*" ], [ "是否有宣传队伍*" ], [ "有，宣传队伍信息", "宣传队伍人数*" ], [ "有，宣传队伍信息", "姓名*" ], [ "有，宣传队伍信息", "部门*" ], [ "有，宣传队伍信息", "职务*" ], [ "是否有新闻员*" ], [ "有，新闻员信息", "姓名*" ], [ "有，新闻员信息", "职务*" ], [ "有，新闻员信息", "级别*" ], [ "有，新闻员信息", "联系电话*" ], [ "日常宣传渠道数量（种）" ], [ "具体渠道" ], [ "最常用的三种宣传渠道", "常用渠道一", "名称*" ], [ "最常用的三种宣传渠道", "常用渠道一", "网址*" ], [ "最常用的三种宣传渠道", "常用渠道二", "名称*" ], [ "最常用的三种宣传渠道", "常用渠道二", "网址*" ], [ "最常用的三种宣传渠道", "常用渠道三", "名称*" ], [ "最常用的三种宣传渠道", "常用渠道三", "网址*" ], [ "是否是教育部信息直报点院校*" ], [ "是，直报员信息", "姓名*" ], [ "是，直报员信息", "职务*" ], [ "是，直报员信息", "联系电话*" ], [ "校验结果" ], [ "校验状态" ], [ "状态" ] ]

使用以上请求头数据序列化为List<List>后注入可以清晰的看到错误。

Current Behavior

在有，总负责人信息下，在旧版easyExcel中可以正常合并姓名*，职务*等列，但是在最新2.0.2版本中无法合并

Expected Behavior

姓名*，职务*等列可以正常合并

Please refer to the header merge strategy.

是可以的，调整了合并策列以后，问题已经解决了。
文档里应当可以添加对于默认自动合并策略细节的更多描述。
如果我读源码理解了完整策略我会尝试补充一下。
