-## 1. Grouping (分组)
+## 1. Sorting (排序)
+
+### 功能描述 (Feature Description)
+
+行排序功能允许用户对表格数据按一个或多个列进行排序，类似 Airtable 的排序体验。
+
+The row sorting feature allows users to sort table data by one or multiple columns, similar to Airtable's sorting experience.
+
+### 使用方法 (Usage)
+
+#### GridView 组件
+
+```tsx
+import { GridView, SortConfig } from '@objectql/ui'
+
+function MyComponent() {
+  const [sorts, setSorts] = useState<SortConfig[]>([])
+
+  return (
+    <GridView
+      columns={columns}
+      data={data}
+      enableSorting={true}
+      onSortChange={(newSorts) => setSorts(newSorts)}
+    />
+  )
+}
+```
+
+### 特性 (Features)
+
+- ✅ 单列排序：点击列标题排序
+- ✅ 多列排序：Shift + 点击添加多个排序级别
+- ✅ 排序指示器：显示排序方向 (↑ 升序 / ↓ 降序)
+- ✅ 排序优先级：多列排序时显示优先级数字 (1, 2, 3...)
+- ✅ 智能排序：根据数据类型自动选择排序算法
+- ✅ 可配置：可以禁用特定列的排序
+
+### 排序行为 (Sorting Behavior)
+
+**单列排序 (Single Column Sort):**
+1. 第一次点击：升序 (A→Z, 0→9, 旧→新)
+2. 第二次点击：降序 (Z→A, 9→0, 新→旧)
+3. 第三次点击：清除排序
+
+**多列排序 (Multi-Column Sort):**
+1. 按住 Shift 键点击列标题
+2. 可添加多个排序级别
+3. 先按第一个排序字段，再按第二个，以此类推
+
+**数据类型排序 (Data Type Sorting):**
+- `text`: 不区分大小写的字母排序
+- `number`: 数值比较
+- `date`: 按时间顺序
+- `boolean`: false 在前，true 在后
+- `null/undefined`: 始终排在最后
+
+### API
+
+**SortConfig 类型:**
+
+```typescript
+interface SortConfig {
+  columnId: string
+  direction: 'asc' | 'desc'
+}
+```
+
+**Column 属性:**
+
+```typescript
+interface Column {
+  id: string
+  label: string
+  sortable?: boolean  // 默认 true，设为 false 可禁用该列排序
+  // ... 其他属性
+}
+```

+
+### Sorting
+
+GridView supports single and multi-column sorting similar to Airtable:
+
+**Single Column Sorting:**
+- Click on a column header to sort ascending
+- Click again to sort descending
+- Click a third time to remove sorting
+
+**Multi-Column Sorting:**
+- Hold Shift and click column headers to add additional sort levels
+- Each sorted column shows its sort direction (↑ for ascending, ↓ for descending)
+- Multi-column sorts show sort priority numbers (1, 2, 3, etc.)
+
+**Example:**
+
+```tsx
+import { GridView, SortConfig } from '@objectql/ui'
+
+function MyComponent() {
+  const [sorts, setSorts] = useState<SortConfig[]>([])
+
+  const handleSortChange = (newSorts: SortConfig[]) => {
+    setSorts(newSorts)
+    console.log('Active sorts:', newSorts)
+    // Example output: [
+    //   { columnId: 'priority', direction: 'desc' },
+    //   { columnId: 'name', direction: 'asc' }
+    // ]
+  }
+
+  return (
+    <GridView
+      columns={columns}
+      data={data}
+      enableSorting={true}
+      onSortChange={handleSortChange}
+    />
+  )
+}
+```
+
+**Disabling Sorting for Specific Columns:**
+
+```tsx
+const columns = [
+  { id: 'name', label: 'Name', sortable: true },
+  { id: 'actions', label: 'Actions', sortable: false }, // No sorting for this column
+]
+```
+
+**Sorting Behavior:**
+- Text fields: Case-insensitive alphabetical sorting
+- Number fields: Numeric comparison
+- Date fields: Chronological sorting
+- Boolean fields: false before true
+- Null/undefined values: Always sorted to the end
+
 ### Toolbar & ViewSwitcher
 
 Toolbar provides a consistent header for your views with title, actions, and view switching.
