 | ellipsis-component | `'ellipsis' \| 'performant-ellipsis'` | `'ellipsis'` | Component for rendering text ellipsis. It works when `ellipsis` is `EllipsisProps`. If it's `'ellipsis'`, table will use regular `n-ellipsis` component to render text ellipsis. If it's `'performant-ellipsis'`, table will use `n-performant-ellipsis` to render text ellipsis. In the later situation, rendering speed will be much faster but component inside table cell would be unmounted & remounted. | 2.35.0 |
 | expandable | `(rowData: object) => boolean` | `undefined` | Whethe the row is expandable. Only works when `type` is `'expand'`. |  |
