示例1: if
/** Maps to what groups the source row belongs by returning the data of those groups.
*
* @returns a list of data for the rows the argument belongs to. In common cases this list will
* contain only one entry. An empty list means that the source item will be placed in the root of
* this proxyModel. There is no support for hiding source items.
*
* Group data can be pre-loaded in the return value so it's added to the cache maintained by this
* class. This is required if you want to have data that is not present in the source model.
