Column 配置详解

interface Column {
  // 基础配置
  type?: 'selection' | 'expand' | 'index' | 'operate'
  label?: string           // 列标题
  prop?: string            // 字段名 (支持 'category.name' 嵌套)
  width?: number | string  // 列宽
  'min-width'?: number     // 最小宽度
  align?: string           // 对齐: left/center/right
  fixed?: 'left' | 'right' // 固定列
  
  // 显示控制
  show?: boolean           // 是否显示 (默认 true)
  sortable?: boolean       // 是否可排序
  
  // 特殊列类型
  slot?: string            // 自定义插槽名
  header?: string          // 自定义表头插槽
  ellipsis?: boolean | number  // 文本溢出 (true=20字符)
  switch?: boolean         // 状态开关
  switchRefresh?: Function // 开关后回调
  image?: boolean          // 图片显示
  preview?: boolean        // 图片预览 (默认 false)
  link?: boolean           // 链接
  link_text?: string       // 链接文本
  route?: string           // Vue 路由 (支持 :id 参数)
  tags?: boolean | number[]  // 标签显示
  mask?: boolean           // 脱敏显示 (****)
  filter?: Function        // 数据过滤函数
  class?: string           // 自定义 CSS 类
  
  // 操作列配置 (type='operate')
  update?: boolean         // 显示编辑按钮 (默认 true)
  destroy?: boolean        // 显示删除按钮 (默认 true)
  
  // 多级表头
  children?: Column[]      // 子列配置
}

搜索表单配置

interface SearchField {
  type: 'input' | 'select' | 'input-number' | 'date' | 'datetime' | 'range'
  label: string           // 标签
  name: string            // 字段名
  api?: string            // 下拉选项 API
  options?: Array<{       // 静态选项
    label: string
    value: string | number
  }>
  placeholder?: string
  default?: any           // 默认值
  props?: object          // 树形选择器 props
  show?: boolean          // 是否显示
}

catch-table Slots

catch-table Methods (ref 调用)

const catchtable = ref()

// 执行搜索
catchtable.value.doSearch(params, merge)

// 打开弹窗
catchtable.value.openDialog(row, title)

// 关闭弹窗
catchtable.value.closeDialog(isReset)

// 重置搜索
catchtable.value.reset()

// 删除
catchtable.value.del(api, id)

// 设置默认参数
catchtable.value.setDefaultParams(params)

// 获取多选 IDs
catchtable.value.getMultiSelectIds()

// 获取当前查询参数
catchtable.value.getTableQuery()

Provide/Inject

// catch-table 提供
provide('closeDialog', (isReset) => {})
provide('refresh', () => {})

// 在 create.vue 中使用
const closeDialog = inject('closeDialog')
const refresh = inject('refresh')

<script lang="ts" setup>
import { inject, onMounted, ref } from 'vue'
import { useCreate } from '@/composables/curd/useCreate'
import { useShow } from '@/composables/curd/useShow'
import http from '@/support/http'

const props = defineProps<{
  primary?: string | number
  api: string
}>()

// CRUD composables
const { formData, form, loading, submitForm, close } = useCreate(props.api, props.primary)

// 编辑模式加载数据
if (props.primary) {
  useShow(props.api, props.primary, formData)
}

// 关闭弹窗
const closeDialog = inject('closeDialog')
onMounted(() => {
  close(() => closeDialog?.())
})

// 加载分类选项
const categories = ref([])
onMounted(async () => {
  const res = await http.get('categories')
  categories.value = res.data.data
})
</script>

特殊列用法

嵌套字段

{ label: '分类', prop: 'category.name' }  // 访问关联对象

图片列

{ label: '图片', prop: 'image', image: true }           // 不可预览
{ label: '图片', prop: 'image', image: true, preview: true }  // 可预览

链接列

{ label: '链接', prop: 'url', link: true }
{ label: '链接', prop: 'url', link: true, link_text: '查看' }

路由链接

{ label: '详情', prop: 'name', route: '/product/detail/:id' }

标签列

{ label: '状态', prop: 'status', tags: true }  // 默认样式
{ label: '状态', prop: 'status', tags: ['success', 'danger', 'warning'] }

数据过滤

{ 
  label: '价格', 
  prop: 'price', 
  filter: (val) => `¥${val.toFixed(2)}`
}

脱敏显示

{ label: '手机', prop: 'mobile', mask: true }  // 138****8888

树形表格

<catch-table
  :columns="columns"
  api="categories"
  row-key="id"
  :pagination="false"
>

后端需返回嵌套结构或使用 asTree() 方法。
