- 1.從工具箱拉出表或者矩陣（本次使用的是矩陣）
- 2.選擇需要的數據集，沒有就新建一個數據集，名稱自己起好，下面有用到
- 3.將行組和行列顯示出來（右擊報表--試圖=>）
- 4.雙擊行組下的RowGroup組=>常規=>組表達式=>分組方式，點擊FX 選擇類別=>字段（DbSetName）=>雙擊右邊的值（選擇你要的分組依據），或者直接點擊頁面矩陣上行右上角的圖標添加分組依據（第3步圖）。
- 5.右擊行組--RowGroup組，添加組=>子組,同第3步一樣 fx 之后的步驟
6.如果在這個組下有其他數據要展示，右擊你添加好的行組所在視圖的文本框=>插入列=>組內部-右側（位置左右自己挑）
7.后台代碼
var list=XXX，在數據層拿到T-SQL數據
直接輸出為PDF下載到本地
excel格式：
