       "motivation": "setRows 已支持整体换源并按 rowKey 剔除失效选择，但列定义仍是构造时写死：动态列表（按角色 / 视图切换列集）只能重建整个实例，排序与筛选状态全丢；setColumns 与 setRows 对称——换列后指向不存在列的 sorting / filters 失去语义，应剔除而不是静默残留。",
       "acceptance": "① core 新增 setColumns(next)：引用未变不动；换列后剔除 sorting / filters 里 key 不在新列集的条目，其余状态（分页 / 选择）保持；② getColumns 返回最新列集，getCellValue 按新列 accessor 取值；③ smoke 冒烟补断言（失效剔除 + 未变短路 + accessor 跟随）；④ npm run check 通过。",
