关于层次数据的配置，在数据源的模型中可以看到如下配置：
SpreadJS TableSheet的层次数据支持有四种不同的层次结构: Parent（父子）, Level（等级层次）, ChildrenPath（子路径）, Custom（自定义）.
在向数据管理器添加表的时候，可以对每一项进行配置。
配置父子层次结构类型：
配置等级层次结构类型：
配置子路径层次结构类型：
配置自定义层次结构类型：
有一些操作可以更新TableSheet中的层次结构记录。
1.提升一个数据的层级:
2.降低一个数据的层级:
3.上移:
4.下移:
5.在指定行前插入新数据:
6.在指定行后插入新数据:
7.添加一个新的行数据作为指定行的父行:
8.添加一个新的行数据作为指定行的子行。:
9.展开所有层级:
10.收起所有层级:
11.按指定层级展开:
在TableSheet选项中，有一些选项可以切换分层记录的菜单项的可见性。
要在TableSheet中显示层次结构菜单项：
