### 1.4 Alpine.js 数据结构

```javascript
function dataTable() {
  return {
    rows: [],         // 由 Django 后端渲染 JSON 或 HTMX 注入
    selected: [],     // 选中行 ID 数组
    sortKey: '',
    sortDir: 'asc',

    get allSelected() {
      return this.rows.length > 0 && this.selected.length === this.rows.length
    },

    toggleAll(checked) {
      this.selected = checked ? this.rows.map(r => r.id) : []
    },

    sort(key) {
      if (this.sortKey === key) {
        this.sortDir = this.sortDir === 'asc' ? 'desc' : 'asc'
      } else {
        this.sortKey = key
        this.sortDir = 'asc'
      }
      // 触发 HTMX 请求，携带排序参数
      htmx.trigger('#table-container', 'sort-change',
        { key: this.sortKey, dir: this.sortDir })
    }
  }
}
```

### 1.5 HTMX 排序集成

```html
<!-- 表格外层容器绑定 HTMX，排序/筛选通过 hx-get 重刷表体 -->
<div id="table-container"
     hx-get="/properties/"
     hx-trigger="sort-change"
     hx-target="#table-body"
     hx-swap="innerHTML"
     hx-include="[name='sort_key'],[name='sort_dir'],[name='q']">
```

## 5. Export Button

### 5.1 两种模式

| 模式 | 触发条件 | 实现方式 |
|---|---|---|
| 同步导出 | 数据量 ≤5000 条 | Django 视图直接返回 `FileResponse`，浏览器触发下载 |
| 异步导出 | 数据量 >5000 条 | Celery 任务异步生成，完成后推送 Toast 通知（含下载链接） |

### 5.2 HTML 结构

```html
<!-- 同步导出（小数据量） -->
<a href="/properties/export/?{{ query_string }}"
   class="inline-flex items-center gap-1.5 px-3 py-1.5 text-sm font-medium rounded-md
          border border-neutral-200 text-neutral-700 bg-white hover:bg-neutral-50">
  <svg class="w-4 h-4" aria-hidden="true"><!-- arrow-down-tray --></svg>
  导出
</a>

<!-- 异步导出（大数据量，HTMX 触发任务） -->
<button hx-post="/properties/export-async/"
        hx-target="#toast-container"
        hx-swap="beforeend"
        class="inline-flex items-center gap-1.5 px-3 py-1.5 text-sm font-medium rounded-md
               border border-neutral-200 text-neutral-700 bg-white hover:bg-neutral-50">

## 8. Tree Select

### 8.1 视觉规格

| 属性 | 值 |
|---|---|
| 触发框 | `h-9 px-3 text-sm border border-neutral-200 rounded-md` |
| 面板宽度 | `w-72` |
| 父节点行高 | `h-9` |
| 子节点行高 | `h-9 pl-8`（左缩进） |
| 展开箭头 | `w-4 h-4 transition-transform`，展开时 `rotate-90` |
| 已选节点 | `bg-primary-50 text-primary-700` |
| 带头像叶节点 | `w-6 h-6 rounded-full bg-primary-100 text-primary-700 text-xs flex items-center justify-center` |
| Badge（关闭状态） | `bg-warning-50 text-warning-600 text-xs px-1.5 py-0.5 rounded-full` |
| 底部操作行 | `sticky bottom-0 border-t border-neutral-100 bg-white px-3 py-2` |

### 8.2 推荐实现方案

**方案一（默认，数据量 ≤200 节点）**：后端一次性返回完整 JSON，Alpine.js 前端递归渲染

**方案二（数据量大）**：HTMX 懒加载子节点（点击展开时 `hx-get` 请求子数据）

### 8.3 HTML 结构（方案一）

```html

## 9. Date Range Picker

### 9.1 技术选型

**使用 Flatpickr**（CDN，~16KB，无框架依赖），不手写。

```html
<!-- CDN 引入 -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/flatpickr/dist/flatpickr.min.css">
<script src="https://cdn.jsdelivr.net/npm/flatpickr"></script>
<script src="https://cdn.jsdelivr.net/npm/flatpickr/dist/l10n/zh.js"></script>
```

### 9.2 初始化配置

```javascript
flatpickr('#dateRange', {
  mode: 'range',
  showMonths: 2,
  locale: 'zh',
  dateFormat: 'Y-m-d',
  allowInput: true,
  onReady(_sel, _str, fp) {
    fp.calendarContainer.classList.add('fonrey-calendar')
  }
})
```

### 9.3 样式覆盖（配合主色 Teal）

```css
/* static/css/flatpickr-overrides.css */
.flatpickr-day.selected,
.flatpickr-day.startRange,
.flatpickr-day.endRange {
  background: #0F766E;
  border-color: #0F766E;
}
.flatpickr-day.inRange {
  background: #CCFBF1;
  border-color: #CCFBF1;
  color: #115E59;
}
.flatpickr-day.today {
  border-color: #D97706;
}
```

### 9.4 HTML 结构

```html
<div class="relative">
  <label class="block text-sm font-medium text-neutral-700 mb-1">日期范围</label>
  <div class="relative">
    <svg class="absolute left-3 top-1/2 -translate-y-1/2 w-4 h-4 text-neutral-400 pointer-events-none"
         aria-hidden="true"><!-- calendar --></svg>
    <input type="text" id="dateRange" name="date_range"
           placeholder="开始日期 → 结束日期"
           class="w-full pl-9 pr-3 py-2 text-sm border border-neutral-200 rounded-md
                  focus:outline-none focus:ring-2 focus:ring-primary-600/40"
           readonly>
  </div>
</div>

    reset: true, rotateLeft: true, rotateRight: true, download: true,
  },
  navbar: true,
  title: (image) => `${image.alt} · ${image.naturalWidth} × ${image.naturalHeight}`,
  url: 'data-src',  // 使用 data-src 存储原图 URL
})
```

## 19. Sortable Table with Drag Handle

### 19.1 技术选型

**SortableJS**（CDN，~3KB），与 Alpine.js 集成，处理拖拽排序。

### 19.2 视觉规格

| 属性 | 值 |
|---|---|
| 拖拽手柄 | `cursor-grab active:cursor-grabbing text-neutral-300 hover:text-neutral-500` |
| 拖拽中行 | `.sortable-chosen`：`bg-primary-50 shadow-md` |
| 放置占位行 | `.sortable-ghost`：`border-2 border-dashed border-primary-300 bg-transparent opacity-50` |

### 19.3 HTML 结构

```html
<div x-data="sortableTable()">
  <table class="min-w-full divide-y divide-neutral-200">
    <thead class="bg-neutral-50">
      <tr>
        <th class="w-8 px-2"></th><!-- 手柄列 -->
        <th class="px-4 py-3 text-left text-xs font-semibold text-neutral-500 uppercase">字段名称</th>
        <!-- 其他列头 -->
      </tr>
    </thead>
    <tbody id="sortable-table" class="bg-white divide-y divide-neutral-100" x-init="initSort()">
      <template x-for="row in rows" :key="row.id" :data-id="row.id">
        <tr class="hover:bg-neutral-50">
          <!-- 拖拽手柄 -->
          <td class="px-2 py-3">
            <div class="drag-handle cursor-grab active:cursor-grabbing text-neutral-300 hover:text-neutral-500 w-5 h-5 flex items-center justify-center"
                 aria-hidden="true">
              <svg class="w-4 h-4"><!-- bars-3 / grip-vertical --></svg>
            </div>
          </td>
          <td class="px-4 py-3 text-sm text-neutral-800" x-text="row.name"></td>
        </tr>
      </template>
    </tbody>
  </table>
</div>
```

### 19.4 Alpine.js + SortableJS 初始化

```javascript
function sortableTable() {
  return {
    rows: [],

    initSort() {
      Sortable.create(document.getElementById('sortable-table'), {
        handle: '.drag-handle',
        animation: 150,
        chosenClass: 'bg-primary-50 shadow-md',
        ghostClass: 'sortable-ghost',

        onEnd: (evt) => {
          const moved = this.rows.splice(evt.oldIndex, 1)[0]
          this.rows.splice(evt.newIndex, 0, moved)
          this.saveOrder()
        }
      })
    },

    saveOrder() {
      fetch('/api/field-options/reorder/', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'X-CSRFToken': getCookie('csrftoken')
        },
        body: JSON.stringify({ ids: this.rows.map(r => r.id) })
      })
    }
  }
}
```

```css
/* Drop 占位行样式（在 static/css/app.css 中定义，不写 inline） */
.sortable-ghost {
  border: 2px dashed #5EEAD4; /* primary-300 */
  background: transparent !important;
  opacity: 0.5;
}
```

## 20. Multi-Table Independent Pagination

### 20.1 核心设计原则

每个表格区块拥有**独立的三要素**，通过 HTMX `hx-target` 精准隔离：

```
表格区块 N
  ├─ id="table-{module}"        ← 唯一 DOM 目标
  ├─ hx-target="#table-{module}" ← 分页只刷新自身
  └─ /api/{module}/?page=N       ← 独立后端分页接口
```

翻某个表格的页，其他表格 **DOM 完全不变**。

### 20.2 HTML 结构

```html
<!-- 顶部搜索（刷新全部表格） -->
<form hx-get="/params/search/"
      hx-target="#all-tables"
      hx-swap="innerHTML"
      class="flex items-center gap-2 mb-4">
  <input type="text" name="q" placeholder="搜索参数名称"
         class="px-3 h-9 text-sm border border-neutral-200 rounded-md flex-1 focus:outline-none focus:ring-2 focus:ring-primary-600/40">
  <button type="submit"
          class="px-4 h-9 text-sm font-medium text-white bg-primary-600 rounded-md hover:bg-primary-700">
    搜索
  </button>
  <button type="button"
          hx-get="/params/"
          hx-target="#all-tables"
          class="px-4 h-9 text-sm font-medium text-neutral-700 border border-neutral-200 rounded-md hover:bg-neutral-50">
    重置
  </button>
</form>

<!-- 所有表格容器 -->
<div id="all-tables" class="space-y-6">

  <!-- 表格区块：业客信息 -->
  <section>
    <div class="mb-2">
      <h3 class="text-sm font-semibold text-neutral-800">业客信息</h3>
      <p class="text-xs text-neutral-500 mt-0.5">买卖双方及关联人员信息字段</p>
    </div>

    <!-- 表格内容区（分页只刷新此 div） -->
    <div id="table-customer" class="border border-neutral-200 rounded-lg overflow-hidden">
      {% include "partials/table_customer.html" %}
    </div>

    <!-- 独立分页器 -->
    <div class="flex justify-end mt-2">
      {% include "partials/pagination.html" with target="#table-customer" url_base="/params/customer/" page_obj=customer_page %}
    </div>
  </section>

  <!-- 表格区块：合同应收费用 -->
  <section>
    <div class="mb-2">
      <h3 class="text-sm font-semibold text-neutral-800">合同-应收费用</h3>
    </div>

    <div id="table-fee" class="border border-neutral-200 rounded-lg overflow-hidden">
      {% include "partials/table_fee.html" %}
    </div>

    <div class="flex justify-end mt-2">
      {% include "partials/pagination.html" with target="#table-fee" url_base="/params/fee/" page_obj=fee_page %}
    </div>
  </section>

</div>
```

### 20.3 分页器 Partial 模板（可复用）

```html
{# templates/partials/pagination.html #}
{# 参数：target（HTMX 目标）、url_base（接口基础 URL）、page_obj #}
<nav class="inline-flex items-center gap-1" aria-label="分页">
  <button class="w-8 h-8 flex items-center justify-center rounded-md text-neutral-600 hover:bg-neutral-100 disabled:opacity-40"
          {% if not page_obj.has_previous %}disabled{% endif %}
          hx-get="{{ url_base }}?page={{ page_obj.previous_page_number }}"
          hx-target="{{ target }}"
          hx-swap="innerHTML">
    <svg class="w-4 h-4" aria-hidden="true"><!-- chevron-left --></svg>
  </button>

  {% for num in page_range %}
    {% if num == page_obj.number %}
      <span class="w-8 h-8 flex items-center justify-center rounded-md bg-primary-600 text-white text-sm font-medium">{{ num }}</span>
    {% elif num == '…' %}
      <span class="px-1 text-neutral-400">…</span>
    {% else %}
      <button class="w-8 h-8 flex items-center justify-center rounded-md text-sm text-neutral-600 hover:bg-neutral-100"
              hx-get="{{ url_base }}?page={{ num }}"
              hx-target="{{ target }}"
              hx-swap="innerHTML">{{ num }}</button>
    {% endif %}
  {% endfor %}

  <button class="w-8 h-8 flex items-center justify-center rounded-md text-neutral-600 hover:bg-neutral-100 disabled:opacity-40"
          {% if not page_obj.has_next %}disabled{% endif %}
          hx-get="{{ url_base }}?page={{ page_obj.next_page_number }}"
          hx-target="{{ target }}"
