Description
目前是用一个set存的所有已展开行的key，然后到这里react就会重新渲染所有已展开的行，造成不必要的开销。是否应该将是否展开作为行数据的一个属性，配合key，react就可以做到精准更新这一行。
目前的方案还存在一个问题，数据源改变后 #mergedExpandedKeys并没有改变，当数据源重新变回来后又以展开状态渲染了表格。

Research direction
Start by reading the linked section of src/Body/BodyRow.tsx and the mergedExpandedKeys logic in src/hooks/useExpand.ts. Reproduce expansion with a changed data source, then verify that toggling one row does not rerender unrelated expanded rows and that restored data does not regain an outdated expanded state.
