## 1. 快速开始（三步走）

### 第一步：定义列和按钮（`created()` 中）

```js
import { useTableColumns } from '@/composables/useTableColumns'
import { useTableButtons } from '@/composables/useTableButtons'
import { i18nMixin } from '@/composables/useI18n'

export default {
  mixins: [i18nMixin('page.模å<C2A1>—å<E28094>?二级模å<C2A1>—.三级模å<C2A1>—')],

  created () {
    // --- 列定�---
    // å<>ªéœ€å£°æ˜Ž prop å’?label，idx 自动补é½<C3A9>
    // prop: '_actions' 约定为æ“<C3A6>作列，自动渲æŸ?rowButtons
    this.columns = useTableColumns([
      { prop: 'sort', label: this.key('sort'), width: 80 },
      { prop: 'code', label: this.key('code'), minWidth: 120 },
      { prop: 'name', label: this.key('name') },
      { prop: '_actions', label: this.key('operation'), width: 160, fixed: 'right' }
    ])

    // --- 按钮定义 ---
    // ä¸<C3A4>å†<C3A5>分开å†?buttonList / tableButtonList
    const btns = useTableButtons({
      toolbar: [
        { key: 'add', label: this.key('add'), icon: 'el-icon-plus',
          type: 'primary', auth: '/xxx/create', onClick: this.openAdd }
      ],
      row: [
        { key: 'edit', label: this.key('edit'), icon: 'el-icon-edit',
          auth: '/xxx/edit', onClick: this.openEdit },
        { key: 'delete', label: this.key('delete'), icon: 'el-icon-delete',
          color: 'danger', auth: '/xxx/delete', onClick: this.handleDelete }
      ]
    }, this.$permission) // â†?第二个å<C2AA>‚æ•°ä¼ å…¥æ<C2A5>ƒé™<C3A9>校验函æ•?
    this.toolbarButtons = btns.toolbarButtons
    this.rowButtons = btns.rowButtons
  }
}
```

### 第二步：写模æ<C2A1>¿ï¼ˆ`<template>` 中）

```vue
<template>
  <d2-container>
    <!-- æ<EFBFBD>œç´¢åŒ?-->
    <template #header>
      <el-form :inline="true" size="mini">
        <el-form-item :label="$t(key('code'))">
          <el-input v-model="search.code" :placeholder="$t(key('enter_code'))"
                    clearable style="width:200px" @keyup.enter.native="onSearch" />
        </el-form-item>
        <el-form-item>
          <el-button type="primary" icon="el-icon-search" @click="onSearch">
            {{ $t(key('search')) }}
          </el-button>
          <el-button icon="el-icon-refresh" @click="onReset">
            {{ $t(key('reset')) }}
          </el-button>
        </el-form-item>
      </el-form>
    </template>

    <!-- 表格 + 按钮�+ 分页 -->
    <page-table
      :columns="columns"
      :data="tableData"
      :loading="loading"
      :toolbar-buttons="toolbarButtons"
      :row-buttons="rowButtons"
      :pagination="pagination"
      help-url="/help/your-page"
      auto-height
      @page-change="onPageChange"
      @selection-change="onSelect"
    />

    <!-- 新增/编辑弹框 -->
    <page-dialog-form
      ref="dialogForm"
      :visible.sync="dialogVisible"
      :title="dialogTitle"
      width="35%"
      :form-cols="formCols"
      :form-data="formData"
      :rules="rules"
      :submitting="submitting"
      :confirm-text="$t(key('confirm'))"
      :cancel-text="$t(key('cancel'))"
      @submit="onDialogSubmit"
      @close="onDialogClose"
    />
  </d2-container>
</template>
```

### 第三步：写业务方法（增删改查�
```js
methods: {
  // 获å<C2B7>–列表数æ<C2B0>®
  async fetchData () {
    this.loading = true
    try {
      const res = await getList({
        ...this.search,
        page_no: this.pagination.current,
        page_size: this.pagination.size
      })
      this.tableData = res.data || []
      this.pagination.total = res.count || 0
    } finally { this.loading = false }
  },

  // æ<>œç´¢ / é‡<C3A9>ç½®
  onSearch () { this.pagination.current = 1; this.fetchData() },
  onReset () { this.search = { code: '', name: '' }; this.pagination.current = 1; this.fetchData() },

  // 分页å<C2B5>˜åŒ–
  onPageChange (page) {
    this.pagination.current = page.current
    this.pagination.size = page.size
    this.fetchData()
  },

  // 新增：打开弹窗
  openAdd () {
    this.handleType = 'create'
    this.dialogTitle = this.key('add_title')
    this.$nextTick(() => {
      this.$refs.dialogForm.reset()
      this.resetForm()
      this.dialogVisible = true
    })
  },

  // 编辑：回填表å<C2A8>?  openEdit (row) {
    this.handleType = 'edit'
    this.dialogTitle = this.key('edit_title')
    this.editId = row.id
    this.formData = { code: row.code, name: row.name }
    this.dialogVisible = true
  },

  // æ<><C3A6>交表å<C2A8>•
  async onDialogSubmit () {
    this.submitting = true
    try {
      if (this.handleType === 'create') {
        await createApi(this.formData)
      } else {
        await editApi({ ...this.formData, id: this.editId })
      }
      this.$message.success(this.$t(this.key('operation_success')))
      this.dialogVisible = false
      this.fetchData()
    } finally { this.submitting = false }
  },

  // 关闭弹窗
  onDialogClose () { this.resetForm() },

  // 删除
  async handleDelete (row) {
    try {
      await this.$confirm(
        this.$t(this.key('confirm_delete')),
        this.$t(this.key('tip')),
        { confirmButtonText: this.$t(this.key('confirm')),
          cancelButtonText: this.$t(this.key('cancel')),
          type: 'warning', closeOnClickModal: false }
      )
      await deleteApi({ id: [row.id] })
      this.$message.success(this.$t(this.key('operation_success')))
      this.fetchData()
    } catch (e) { /* å<>–消或失è´?*/ }
  }
}
```

  { prop: '_actions', label: 'æ“<C3A6>作', width: 160, fixed: 'right' }  // â†?æ“<C3A6>作åˆ?])
```

**内部约定**：`prop === '_actions'` 自动标记ä¸?`slot: '_actions'`，由 `page-table` 渲染为æ“<C3A6>作列ã€?
---

### 4.2 `useTableButtons(options, permissionCheck?)`

**作用**：统一生æˆ<C3A6>工具æ <C3A6>按钮和行内æ“<C3A6>作按钮，自动注入æ<C2A5>ƒé™<C3A9>校验结果ã€?
| å<>‚æ•° | 类型 | 说明 |

## 5. i18n 国际化方�
### 5.1 语言包文�
| 语言 | 文件路径 |
|------|---------|
| 简体中�| `src/locales/zh-chs.json` |
| ç¹<C3A7>体中文 | `src/locales/zh-cht.json` |
| 英文 | `src/locales/en.json` |
| 日文 | `src/locales/ja.json` |

### 5.2 语言包结�
æŒ?`一级模å<C2A1>?â†?二级模å<C2A1>— â†?三级模å<C2A1>—` 三层嵌套ï¼?
```json
{
  "page": {
    "production_master_data": {
      "factory_model": {
        "factory_area": {
          "search": "查询",
          "reset": "é‡<C3A9>ç½®",
          "code": "所区编�,

        }
      }
    }
  }
}
```

### 5.3 组件自动翻译

`page-table` �`page-dialog-form` 内置 `$t()`�
- **�label** �自动翻译
- **按钮 label** �自动翻译
- **表å<C2A8>• label / placeholder** â†?自动翻译
- **弹框 title / confirm / cancel** �自动翻译

因此页é<EFBFBD>¢å<EFBFBD>ªéœ€ä¼ å…¥ i18n key 字符串，组件渲染时自动替æ<C2BF>¢ä¸ºå½“å‰<C3A5>语言的文本ã€?

</el-form-item>
<el-button>{{ $t(key('search')) }}</el-button>
```

```js
// JS �this.$message.success(this.$t(this.key('operation_success')))
this.$confirm(this.$t(this.key('confirm_delete')), this.$t(this.key('tip')), { ... })
```

## 6. 常用场景速查

### 场景 1：自定义列渲染（状�tag�
列定义加�`slot: true`�
```js
useTableColumns([

      {{ row.status === 1 ? 'å<>¯ç”¨' : 'ç¦<C3A7>用' }}
    </el-tag>
  </template>
</page-table>
```

### 场景 2：工具æ <C3A6>追加自定义按é’?
```vue
<page-table :columns="columns" :toolbar-buttons="toolbarButtons">
  <template #toolbar-extra>
    <el-button size="mini" icon="el-icon-printer" @click="print">打å<EFBFBD>°</el-button>
  </template>
</page-table>
```

### 场景 3：å¤<C3A5>选框åˆ?+ åº<C3A5>å<EFBFBD>·åˆ?
```js
useTableColumns(
  [
    { prop: 'code', label: 'ç¼–ç <C3A7>' },
    { prop: 'name', label: 'å<><C3A5>称' }
  ],
  { selectionWidth: 55, indexWidth: 60 }
)
```

### 场景 4：带下拉选择的表å<C2A8>?
```js
formCols: [
  [
    { type: 'select', prop: 'area_id',
      label: k('area'), placeholder: k('select_area'),
      options: [{ label: 'A厂区', value: 1 }, { label: 'B厂区', value: 2 }],
      clearable: true, style: { width: '90%' } }
  ]
]
```

### 场景 5：批é‡<C3A9>删除（工具æ ?+ 需è¦<C3A8>选中行）

```js
useTableButtons({
  toolbar: [
    { key: 'batchDelete', label: '批é‡<C3A9>删除', icon: 'el-icon-delete',
      type: 'danger', auth: '/xxx/batch-delete',
      needSelection: true,  // â†?需è¦<C3A8>选中行æ‰<C3A6>能点å‡?      onClick: this.batchDelete }
  ]
})
```

### 场景 6：表格自适应高度

å<EFBFBD>ªéœ€åŠ?`auto-height` 属性：

```vue
<page-table ... auto-height />
```

表格高度会自动填æ»?`d2-container` çš?body 区域剩余空间，窗å<E28094>?resize / 侧æ <C3A6>折å<CB9C> æ—¶è‡ªåŠ¨é‡<C3A9>ç®—ã€?
### 场景 7：帮助按�

## 7. 路由é…<C3A9>ç½®

```js
// src/router/modules/production-master-data.js
import layoutHeaderAside from '@/layout/header-aside'

const meta = { auth: true }
const _import = require('@/libs/util.import.' + process.env.NODE_ENV)

export default {

```

之å<EFBFBD>Žåœ?`src/router/routes.js` 中引入该模å<C2A1>—并加å…?`frameIn` 数组ï¼?
```js
import productionConfiguration from './modules/production-master-data'

const frameIn = [
  // ... 其他路由 ...

## 8. API 文件写法

```js
// src/api/production-master-data/factory-area.js
import { request } from '@/api/_service'

const BASE = 'production_master_data/factory_model/factory_area/'

function apiParams (method, data = {}) {
  return {
    method: `production_master_data_factory_model_factory_area_${method}`,
    platform: 'background',
    ...data
  }
}

export function getFactoryAreaList (data) {
  return request({
    url: BASE + 'list',
    method: 'get',
    params: apiParams('list', data)
  })
}

export function createFactoryArea (data) {
  return request({
    url: BASE + 'create',
