vue封装动态表格
悟空和大王 人气:0前言
这里只是提供一种想法并提供一些快速实现,实际这些技巧可以用在很多地方,如:动态表单
实现方式简述
- 通过json定义要显示的列
- 通过slot实现自定义列
- 通过
require.context
实现组件的自动注册,并通过<components is="xxx"></components>
, 调用动态注册的组件
优点:
- 支持通过slot自定义扩展
- 支持编写vue文件扩展列的显示方式
- 支持通过json来控制列顺序和哪些列需要显示哪些不需要
- 能避免封装的table组件越来越复杂
表格实现:
<template> <el-table :data="tableData" style="width: 100%" height="100%"> <el-table-column v-for="column in columnList" :key="column.prop" v-bind="column.columnAttrs" > <template slot-scope="scope"> <slot v-if="column.type === 'slot'" :name="column.slotName" :row="scope.row" ></slot> <components v-else :row="scope.row" :prop="column.prop" :config="column" :is="`column-${column.type}`" ></components> </template> </el-table-column> </el-table> </template> <script> const modules = {}; // 将当前目录以及子目录中的index.vue自动注册为组件(require.context是webpack提供的,如果是vite要用vite的方式) const files = require.context("./", true, /index.vue$/); files.keys().forEach((item) => { const name = item.split("/")[1]; modules[`column-${name}`] = files(item).default; }); console.log(modules, "modules"); export default { name: "CustomTable", components: { // 组件动态注册 ...modules, }, props: { tableData: { type: Array, default: () => [], }, columnList: { type: Array, default: () => [], }, }, }; </script> <style scoped></style>
func组件
<template> <span>{{ config.call(row, config) }}</span> </template> <script> export default { name: "ColumnFunc", props: { config: { type: Object, }, row: { type: Object, }, }, }; </script> <style scoped></style>
text组件:
<template> <span>{{ row[config.prop] }}</span> </template> <script> export default { name: "ColumnText", props: { config: { type: Object, }, row: { type: Object, }, }, }; </script> <style scoped></style>
调用示例
<template> <CustomTable :column-list="columnList" :table-data="tableData"> <template #operate="{ row }"> <el-button size="small">删除</el-button> <el-button size="small" type="primary" @click="onEdit(row)"> 编辑 </el-button> </template> </CustomTable> </template> <script> import CustomTable from "@/components/my-table/CustomTable"; export default { name: "CustomTableDemo", components: { CustomTable, }, data() { return { columnList: [ { type: "text", prop: "name", columnAttrs: { label: "姓名", width: "180", }, }, { type: "text", prop: "date", columnAttrs: { label: "日期", width: "180", }, }, { type: "func", prop: "sex", columnAttrs: { label: "性别", }, call: (row) => { switch (row.sex) { case 1: { return "男"; } case 2: { return "女"; } default: { return "未知"; } } }, }, { type: "slot", slotName: "operate", prop: "operate", columnAttrs: { label: "操作", }, }, ], tableData: [ { date: "2016-05-02", name: "王小虎", address: "上海市普陀区金沙江路 1518 弄", sex: 1, }, { date: "2016-05-04", name: "王小虎", address: "上海市普陀区金沙江路 1517 弄", sex: 2, }, { date: "2016-05-01", name: "王小虎", address: "上海市普陀区金沙江路 1519 弄", sex: 3, }, ], }; }, methods: { onEdit(row) { console.log(row); }, }, }; </script> <style scoped></style>
