Ext.js5带子标题的标题的表格（6）

/**
* This example shows how to create a grid with column headers which are nested within
* category headers.
*这个例子展示了怎么怎么创建有子标题的表格。我觉得有个瑕疵就是这个父标题没法控制子标题的显示隐藏。
*这个没有什么大的变化，还是在view中设置列嵌套列就行了。
* Category headers do not reference Model fields via a `dataIndex`, rather they contain
* child header definitions (which may themselves either contain a `dataIndex` or more
* levels of headers).
