交互报表 -- 审核人选择窗口

交互报表中，所有须选择审核人的报表，均可使用该界面，其他情况禁止使用
即 InteractFlag[交互类型]为1时 可用。

将交互报表中的角色名填入第一列，用户在第二列下拉选择审核人

[项目数据库Proj, 当前期数据库Phase, 交互表内容保存至RD数据表]
其中Proj和Phase中均存有1份RD

整个流程可大致分解为4步：
1. 用户切换至报表界面时，将[Phase]RD -拷贝-> [Proj]RD
2. 用户点击该报表时，加载[Proj]RD数据至该窗口
3. 用户可在该窗口更改选择的审核人，用户确认后，将数据保存至[Proj]RD中
4. 用户关闭报表界面时，将[Proj]RD -拷贝-> [Phase]RD
