【场景】做插入行选单处理
【案例】二开实现，针对采购订单选单采购申请单，针对选中行位置插入关联关系行

{
int seq = (int)entityObjColl[i][entity.SeqDynamicProperty];
// 前面的行不处理
if (seq < rowIdx + 1)
continue;
// 本次生成的link数据包，前面已经重置序号了
if (linkObjs.Contains(entityObjColl[i]))
continue;
entityObjColl[i][entity.SeqDynamicProperty] = insertLinkSeq;
++insertLinkSeq;

}
}
}
```
【效果】
这个很实用的
