Description
如果spl最后计算结果为空，就会return null，应用调用时由于没有结构引用字段时就会出错。还要专门创建一个空序表返回。这块能否改进，或有什么更好的办法？

Research direction
Start by tracing the SPL calculation path that returns null for an empty result and the application call path that fails when no structural reference fields are present. Clarify the expected structure of an empty table, then verify that empty calculations return it consistently and that existing non-empty results remain unchanged.
