+## 2026-05-18：数据管理页切换时刷新表列表
+
+- `frontend/src/components/DatabasePanel.vue` 在数据管理页激活时会重新执行 `loadTables()`，确保从其他页面切回时左侧表列表拉取最新状态。
+- 离开数据管理页时会清空表列表、当前选中表和表数据，避免已删除的表在下次进入前短暂残留。
+- 表列表请求增加 `tableLoadToken`，忽略离开页面后返回的旧请求，防止过期响应把已清空的列表重新写回。
+- 已执行 `npm run build`，构建通过；未启动浏览器或 headless Chrome。
+
 ## 2026-05-18：合并数据管理页快速导入检测入口
 
 - `frontend/src/components/DatabasePanel.vue` 移除数据库状态卡片里的独立“重新检测”文字按钮，把刷新动作合并到“快速导入”的状态徽标上。
