- 1.从工具箱拉出表或者矩阵（本次使用的是矩阵）
- 2.选择需要的数据集，没有就新建一个数据集，名称自己起好，下面有用到
- 3.将行组和行列显示出来（右击报表--试图=>）
- 4.双击行组下的RowGroup组=>常规=>组表达式=>分组方式，点击FX 选择类别=>字段（DbSetName）=>双击右边的值（选择你要的分组依据），或者直接点击页面矩阵上行右上角的图标添加分组依据（第3步图）。
- 5.右击行组--RowGroup组，添加组=>子组,同第3步一样 fx 之后的步骤
6.如果在这个组下有其他数据要展示，右击你添加好的行组所在视图的文本框=>插入列=>组内部-右侧（位置左右自己挑）
7.后台代码
var list=XXX，在数据层拿到T-SQL数据
直接输出为PDF下载到本地
excel格式：
