這篇文章主要介紹了vue3?實現(xiàn)關(guān)于?el-table?表格組件的封裝及調(diào)用方法,本文給大家介紹的非常詳細,感興趣的朋友跟隨小編一起看看吧

一、示例圖：

二、組件

<template>
  <div class="sn-table" :class="props.colorType === 1 ? '' : 'bg-scroll'">
    <el-table :data="tableData" :row-class-name="tableRowClassName" height="500" style="width: 100%;"
      :default-sort="[{ prop: '正確率', order: 'descending' },{ prop: '未答題數(shù)', order: 'descending' }]"
      :class="props.colorType === 1 ? '' : 'bg-scroll'">
      <el-table-column align="center" :prop="item.keyName"
        :sortable="item.keyName==='正確率'&&props.isExistSelect||item.keyName==='未答題數(shù)'&&props.isExistSelect?true:false"
        :label="item.keyName" v-for="item in columns"
        :width="item.width ? item.width + 'px' : ''">
        <template #default="scope">
          <div v-if="item.keyName==='正確率'&&props.isExistSelect" class="tag-list">
            <el-progress :percentage="scope.row[item.keyName]" color="#00B386" :stroke-width="10" :text-inside="false"/>
          </div>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>
<script lang='ts' setup>
type TProps = {
  tableData: any[]
  columns: any[],
  colorType: number, // 顏色類型
  isExistSelect: boolean // 是否存在篩選項
}
const props = withDefaults(defineProps<TProps>(), {})
const tableRowClassName = ({ rowIndex }: { rowIndex: number }) => {
  if (rowIndex % 2 === 1) {
    return props.colorType === 1 ? 'odd-row' : 'class-odd-row'
  } else {
    return props.colorType === 1 ? 'even-row' : 'class-even-row'
  }
}
</script>
<style lang='scss' scoped>
.bg-scroll {
  border-radius: 10px;
  height: 96%;
  overflow-y: scroll;
  &::-webkit-scrollbar {
    width: 5px;
    height: 0 !important;
  }
  &::-webkit-scrollbar-thumb {
    border-radius: 10px;
    background: #eeeeee;
  }
}
.sn-table {
  padding: 0 10px 0 20px;
  :deep(.el-table) {
    color: #ffffff !important;
    tr {
      td {
        border: none;
        padding: 16px 0;
        font-size: 15px;
      }
    }
    th.el-table__cell {
      background: #141414 !important;
      border: none;
      color: #00B386;
      font-size: 14px;
      font-weight: 400;
    }
    .even-row {
      background-color: #333 !important;
    }
    .odd-row {
      background-color: #141414 !important;
    }
    .class-even-row {
      background-color: #333 !important;
    }
    .class-odd-row {
      background-color: #00B386 !important;
    }
  }
  :deep(.el-scrollbar__wrap--hidden-default) {
    background: #141414 !important;
  }
  :deep(.el-table--enable-row-hover) {
    .el-table__body {
      tr:hover>td.el-table__cell {
        color: #8C8C8C;
        background: #333 !important;
      }
    }
  }
  :deep(.el-table__inner-wrapper) {
    &::before {
      background-color: transparent;
    }
  }
  :deep(.el-table .ascending .sort-caret.ascending){
    border-bottom-color:#00B386 !important;
  }
  :deep(.el-table .descending .sort-caret.descending){
    border-top-color:#00B386 !important;
  }
  .ok-text{
    font-size: 35px;
    font-weight: 300;
  }
  .tag-list{
    width: 100%;
    padding: 2px 0;
    .tag-btn{
      border-radius: 5px;
      border: 1px solid #EF8714;
      color: #EF8714;
      padding: 1px 10px;
      margin-right: 15px;
      &:last-child{
        margin-right: 0;
      }
    }
  }
}
:deep(.el-progress){
  width: 185px;
  margin: 0 auto;
}
:deep(.el-progress__text){
  span{
    font-size: 16px;
  }
}
:deep(.el-progress-bar__outer){
  background: #D9D9D9;
}
</style>

三、頁面調(diào)用

<details-table :tableData="knowInfo" :columns="knowColumns" :isExistSelect="false" :colorType="1"/>
<script setup lang="ts">
import { onMounted, ref } from 'vue'
import CanvasVideo from "@/components/CanvasVideo.vue"
const knowInfo = ref<any[]>([])
const knowColumns = ref<any[]>([])
onMounted(()=>{
    init()
})
//數(shù)據(jù)處理
const init = () => {
    const datas = ref([
        {studentName:'陳佳穎',correctRate:0,noAnswerCount:13},
        {studentName:'丁靖蕓',correctRate:0,noAnswerCount:13},
        {studentName:'谷雨恒',correctRate:0,noAnswerCount:13},
        {studentName:'歐陽江源',correctRate:0,noAnswerCount:13},
        {studentName:'任行寬',correctRate:0,noAnswerCount:13},
        {studentName:'任彥宇',correctRate:0,noAnswerCount:13},
        {studentName:'王驍南',correctRate:0,noAnswerCount:13},
        {studentName:'吳駿揚',correctRate:0,noAnswerCount:13}
    ])
    if (datas && datas.length > 0) {
        datas.forEach((it: any, index:number) => {
            knowInfo.value.push({
                '行號': index+1,
                '姓名': it.studentName,
                '正確率': it.correctRate,
                '未答題數(shù)': it.noAnswerCount
            })
        })
        for (const key in knowInfo.value[0]) {
            knowColumns.value.push({
                keyName: key,
                width: key === '行號' ? 140 : null
            })
        }
    }
}
</script>

四、其他

（1）自定義標題

<el-table :data="datas" style="width: 100%;">
    <el-table-column label="" prop="name" align="center">
        <template #header>
           姓名
        </template>
    </el-table-column>
</el-table>

（2）自定義下標

<el-table :data="datas" style="width: 100%;">
    <el-table-column label="行號" align="center">
        <template #default="{$index}">
            {{$index+1}}
        </template>
    </el-table-column>
</el-table>

（3）自定義內(nèi)容

<el-table :data="datas" style="width: 100%;">
    <el-table-column label="姓名" prop="name" align="center">
        <template #default="scope">
            <div>{{scope.row.name}}s</div>
        </template>
    </el-table-column>
</el-table>

（4）添加排序（升序、降序）

<el-table :data="datas" style="width: 100%;"
   :default-sort="[{ prop: 'rank', order: 'descending' },{ prop: 'time', order: 'descending' }]">
    <el-table-column label="排名" prop="rank" sortable align="center"/>
    <el-table-column label="時長" prop="time" sortable align="center"/>
</el-table>

（5）多選與單選

1. 單選

<el-table :data="datas" style="width: 100%;"
   row-key="id" ref="multipleTable" highlight-current-row @row-click="rowselect" @selection-change="selectGroupChange">
    <el-table-column type="selection" width="55" />
    <el-table-column label="排名" prop="rank" align="center"/>
    <el-table-column label="時長" prop="time" align="center"/>
</el-table>
<script setup lang="ts">
import { ref } from "vue"
const multipleTable = ref()
const handleList = ref([])
// 設(shè)置單選||顯示高亮
const rowselect = (row:any) => {
  multipleTable.value.toggleRowSelection(row)
}
// 選擇多個單選框，只取最后選中的那一個
const selectGroupChange = (row:any) => {
  if (row.length > 1) {
    multipleTable.value.clearSelection()
    multipleTable.value.toggleRowSelection(row.pop())
    return
  }
  if (row.length == 1) {
    handleList.value = row
  } else {
    handleList.value = []
  }
}
</script>
<style lang='scss' scoped>
// 隱藏表頭選擇框
:deep(.el-table__header){
  .el-checkbox{
    display: none;
  }
}
</style>

2. 多選

<el-table :data="datas" style="width: 100%;"
   row-key="id" @select="handleSelectionChange" @select-all="handleAllChange">
    <el-table-column type="selection" width="55" />
    <el-table-column label="排名" prop="rank" align="center"/>
    <el-table-column label="時長" prop="time" align="center"/>
</el-table>
<script setup lang="ts">
// 選擇多個選擇框
const handleSelectionChange = (selecteds: any, row: any) => {}
// 全選
const handleAllChange= (row:any) => {}
</script>

五、實例（實現(xiàn)樹形數(shù)據(jù)與懶加載）

示例圖：通過點擊當前節(jié)點，調(diào)用接口展示下一節(jié)點，實現(xiàn)列表的增刪改查

1、添加修改組件 EditForm.vue

<template>
  <div>
    <el-form
      ref="menuEditForm"
      :model="form"
      :label-width="formLabelWidth"
      :size="size"
      :rules="rules"
      clearable
    >
      <el-row>
        <el-col :span="12">
          <el-form-item label="父級字典：" prop="parentId">
            <el-cascader ref="myCascader" v-model="form.parentId" :props="{ checkStrictly: true,emitPath:false,expandTrigger:'hover' }" :options="menuTree" :show-all-levels="false" placeholder="請選擇父級字典" clearable />
          </el-form-item>
        </el-col>
        <el-col :span="12">
          <el-form-item label="字典名稱：" :rules="rules.Required" prop="dictionaryName">
            <el-input
              v-model="form.dictionaryName"
              autocomplete="off"
              :show-word-limit="true"
              placeholder="請輸入字典名稱"
            />
          </el-form-item>
        </el-col>
      </el-row>
      <el-row v-if="title==='添加字典'">
        <el-col :span="24">
          <el-form-item label="字典編碼：" :rules="rules.Required" prop="dictionaryCode">
            <el-input
              v-model="form.dictionaryCode"
              autocomplete="off"
              :show-word-limit="true"
              placeholder="請輸入字典編碼"
            />
          </el-form-item>
        </el-col>
      </el-row>
      <el-form-item
        label="備注："
        prop="remark"
      >
        <el-input
          v-model="form.remark"
          type="textarea"
          maxlength="200"
          :show-word-limit="true"
          autocomplete="off"
        />
      </el-form-item>
    </el-form>
  </div>
</template>
<script>

      this.$refs['menuEditForm'].validate((valid) => {
        if (valid) {
          this.loading = true
          EditDictionary(this.form).then((res) => {

        getDictionaryInfo(id).then((res) => {
          if (res.code === 200) {
            this.form = Object.assign(this.form, res.data)
          }
        })
      }
    }
  }
}
</script>

2、主頁面 index.vue

<template>
  <div class="app-container">
    <div class="search-container">
