CrudTable

数据表格 + 分页组件，封装 NDataTable + NPagination，配合 useCrudList 做远端分页 / 排序，配合 useCrudSelection 做行勾选。

Props

Prop	类型	默认值	说明
`list`	`UseCrudListReturn<Row, any>`	—	列表状态（必填）
`columns`	`CrudColumn<Row>[]`	—	列定义（必填）
`selection`	`UseCrudSelectionReturn<Row>`	—	选择状态（传入则开启勾选列）
`rowKey`	`(row: Row) => string \| number`	—	行 key 获取函数（建议传 `adapter.getId`）
`showActionsColumn`	`boolean`	`false`	是否显示操作列（需提供 `row-actions` slot）
`actionsColumnTitle`	`string`	`'操作'`	操作列标题
`actionsColumnWidth`	`number`	`120`	操作列宽度
`tableProps`	`Record<string, unknown>`	—	透传到 `NDataTable`
`paginationProps`	`PaginationProps`	—	透传到 `NPagination`
`getRowActionsSlotProps`	`(row: Row) => Record<string, unknown>`	—	为 `row-actions` slot 注入额外 props

Emits

事件	参数	说明
`sort`	`CrudSort \| null`	排序变化

行为说明

排序

NDataTable 的 sorter 变化会被转换为 core 的 CrudSort，并调用 list.setSort(sort)。远端排序模式（remote）。

分页

NPagination 的页码/每页条数变化调用 list.setPage() / list.setPageSize()
默认显示每页条数选择器（showSizePicker），可选值 [10, 20, 50, 100]

勾选

传入 selection prop 时，自动添加勾选列。勾选变化同步到 selection.select() / selection.clear()。

操作列

当 showActionsColumn 为 true 且提供了 row-actions slot 时，自动添加固定在右侧的操作列。

Slots

Slot	Props	说明
`cell-${key}`	`{ row, value, rowIndex }`	自定义单元格
`row-actions`	`{ row, rowIndex, ...extraProps }`	行操作区
`table-header`	`{ list, selection }`	表格上方区域
