- 封装排序/筛选/分页/导出/列自定义的通用表格
+
 **问题**: 37 个文件各自手写表格（搜索/排序/分页/导出/选择全部重复实现），维护成本高
 **方案**:
 - 封装 `DataTable<T>` 泛型组件（`components/ui/data-table.tsx`），声明式列定义 + 内置功能开关
 - 替换散布在各页面的手写表格
 **已完成 (2026-06-27)**:
 - ✅ 新增 `DataTable<T>` 组件 — 支持声明式列定义、排序（三态 asc/desc/null）、全局搜索（指定字段）、客户端分页（可配置 pageSize）、行选择（受控 selectedIds）、CSV 导出（UTF-8 BOM）、列可见性面板（DropdownMenu toggle）、加载骨架、空状态自定义渲染、行点击、CSS 变量主题适配
 - ✅ 迁移 3 个代表性页面:
  - **RegionManager.tsx** — 区域管理（CRUD + 搜索 + 选择 + 排序 + 导出 + 列可见性 + 云商筛选）
  - **LoginLogsTab.tsx** — 登录日志（搜索 + 排序 + 分页 + 导出 + 列可见性 + 状态筛选）
  - **LogDatasourcePage.tsx** — 日志数据源管理（搜索 + 排序 + CRUD + 测试连接）
 - ✅ 所有功能内建（搜索/排序/分页/选择/导出/列可见性），无需在各页面重复实现
 **验收标准**:
 - [x] `DataTable<T>` 组件封装排序/搜索/分页/导出/列自定义/行选择
 - [x] `tsc -b` 零错误，`npm run build` 零错误（✓ built in 18.05s）
 - [x] 迁移的页面功能不变（CRUD/搜索/选择/排序/导出全部保留）
 - [x] ESLint any=43（<50），4 个迁移文件零 ESLint 错误
 - [x] 17/17 集成回归测试通过
