vue3中这样写重复表格更高效

vue3 中如何优雅的使用 el-table

我正在参加「掘金·启航计划」

优点

摆脱繁琐的 繁琐的分页操作表格操作等，以及反复的重复 dom。

想法

将 el-table 封装成一个全局组件. 一切皆可配置.

• api 可配置
• el-table-column
• 分页配置
• 一屏展示内容

用法

const columns = reactive([
  {
    label: "name",
    prop: "name"
  },
  {
    slot: true,
    slotName: "age"
  },
  {
    slot: true,
    slotName: "handle"
  }
])
const getTableData = ()=>{
  //同样你可以返回的是api
  return Promise.resolve(()=>{
    return{
      data:[{name:"yoge",age:"18"}]
      total:1
    }
  })
}
const table = ref()
table.load()

<Gtable :fetch="getTableData" ref="table" :columns="columns">
  <template v-slot:header>
    <el-card v-loading="loading" shadow="never" class="search-wrapper">
      <el-form ref="searchFormRef" :inline="true" :model="searchData">
        <el-form-item prop="username" label="简历模板名称">
          <el-input v-model="searchData.name" placeholder="请输入" />
        </el-form-item>
        <el-form-item>
          <el-button type="primary" :icon="Search" @click="handleSearch">查询</el-button>
          <el-button :icon="Refresh" @click="resetSearch">重置</el-button>
        </el-form-item>
      </el-form>
    </el-card>
  </template>
  <template v-slot:btns>
    <el-button type="primary" :icon="CirclePlus" @click="addNoteTemCate">添加简历模板分类</el-button>
    <el-button type="primary" :icon="CirclePlus" @click="addNoteTem">添加简历模板</el-button>
  </template>
  <template v-slot:age>
    <el-table-column prop="roles" label="age" align="center">
      <template #default="{ row }"> {{row.age}} </template>
    </el-table-column>
  </template>
  <template v-slot:handle>
    <el-table-column fixed="right" label="操作" width="150" align="center">
      <template #default="scope">
        <el-button type="primary" text bg size="small" @click="handleUpdate(scope.row)">修改</el-button>
        <el-button type="danger" text bg size="small" @click="handleDelete(scope.row)">删除</el-button>
      </template>
    </el-table-column>
  </template>
</Gtable>

效果图

表格封装

<template>
  <div class="app-container">
    <slot name="header" />
    <div class="mb-5">
      <slot name="btns" />
    </div>
    <el-table :height="height" :data="tableList.data" border v-loading="loading" ref="table">
      <template v-for="(item, i) in props.columns">
        <slot v-if="item.slot" :name="item.slotName" />
        <el-table-column v-if="!item.slot" v-bind="item" :key="i" />
      </template>
    </el-table>
    <el-pagination
      class="mt-2 float-right"
      background
      :layout="props.layout"
      :page-sizes="props.pageSizes"
      :total="total"
      :page-size="pageSize"
      :currentPage="currentPage"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
    />
  </div>
</template>

<script setup lang="ts">
  import { reactive, ref, Ref, onMounted } from "vue"
  import type { TableInstance } from "element-plus"
  import type { columnsType } from "./types/index"
  const props = defineProps({
    columns: {
      type: Array as () => columnsType[],
      default: () => []
    },
    fetch: {
      type: Function,
      required: true
    },
    layout: {
      type: String,
      default: " total, prev, pager, next"
    },
    pageSizes: {
      type: Array as () => number[],
      default: () => [10, 20, 50, 100]
    },
    pageSize: {
      type: Number,
      default: 10
    },
    currentPage: {
      type: Number,
      default: 1
    }
  })
  const tableList = reactive({ data: [] })
  const table: Ref<TableInstance | null> = ref(null)
  const total = ref(0)
  const height = ref(0)
  const currentPage = ref(1)
  const pageSize = ref(10)
  const loading = ref(false)
  const handleSizeChange = () => {}
  const handleCurrentChange = () => {}
  const load = async () => {
    loading.value = true
    const data = await props.fetch(params)
    tableList.data = data.data
    total.value = data.total
    loading.value = false
  }
  onMounted(() => {
    updataHeight()
    window.addEventListener("resize", updataHeight)
  })
  const updataHeight = () => {
    nextTick(() => {
      const $el = table.value && table.value.$el
      let h = 0
      const indexs = [0, 1, 3]

      indexs.forEach((index) => {
        h += $el.parentNode.children[index].offsetHeight
      })
      height.value = $el.parentNode?.offsetHeight - h - 65
      console.log(height.value, "height")
    })
  }
  defineExpose({ load, updataHeight })
</script>

<style lang="scss" scoped>
  .app-container {
    height: calc(100vh - 90px);
    overflow: scroll;
  }
</style>

• fetch 外部定义获取列表函数
• load 获取表格函数
