table组件如何动态配置表头，toggled可以支持表达式吗？

#### 实现场景：
同一个表格有一些列需要根据类型不同展示或隐藏

#### 存在的问题：
无法动态配置表头或用表达式配toggled

#### 当前方案：
当前方案就是配置多个表格，用visibleOn控制整个表格的显隐

Start by locating the table component and the configuration handling for column visibility, especially `toggled` and `visibleOn`. Clarify whether dynamic headers, expression-based `toggled`, or both are required, then inspect existing table configuration tests if available. Done should mean columns can be shown or hidden by the table's type-dependent configuration without duplicating whole tables.
