一、示例图：

二、组件

  4.       :default-sort="[{ prop: '正确率', order: 'descending' },{ prop: '未答题数', order: 'descending' }]"
  5.       :class="props.colorType === 1 ? '' : 'bg-scroll'">
  6.       <el-table-column align="center" :prop="item.keyName"
  7.         :sortable="item.keyName==='正确率'&&props.isExistSelect||item.keyName==='未答题数'&&props.isExistSelect?true:false"
  8.         :label="item.keyName" v-for="item in columns"
  9.         :width="item.width ? item.width + 'px' : ''">
  10.         <template #default="scope">
  11.           <div v-if="item.keyName==='正确率'&&props.isExistSelect" class="tag-list">
  12.             <el-progress :percentage="scope.row[item.keyName]" color="#00B386" :stroke-width="10" :text-inside="false"/>
  13.           </div>
  14.         </template>
  15.       </el-table-column>
  16.     </el-table>
  17.   </div>
  18. </template>
  19. <script lang='ts' setup>
  20. type TProps = {

  25. }
  26. const props = withDefaults(defineProps<TProps>(), {})

  35. </script>
  36. <style lang='scss' scoped>
  37. .bg-scroll {

  138. :deep(.el-progress-bar__outer){
  139.   background: #D9D9D9;
  140. }
  141. </style>

三、页面调用

  1. <details-table :tableData="knowInfo" :columns="knowColumns" :isExistSelect="false" :colorType="1"/>
  2.  
  3. <script setup lang="ts">
  4. import { onMounted, ref } from 'vue'
  5. import CanvasVideo from "@/components/CanvasVideo.vue"
  6.  
  7. const knowInfo = ref<any[]>([])
  8. const knowColumns = ref<any[]>([])
  9.  
  10.  
  11. onMounted(()=>{
  12.     init()
  13. })
  14.  
  15. //数据处理
  16. const init = () => {
  17.     const datas = ref([
  18.         {studentName:'陈佳颖',correctRate:0,noAnswerCount:13},
  19.         {studentName:'丁靖芸',correctRate:0,noAnswerCount:13},
  20.         {studentName:'谷雨恒',correctRate:0,noAnswerCount:13},
  21.         {studentName:'欧阳江源',correctRate:0,noAnswerCount:13},
  22.         {studentName:'任行宽',correctRate:0,noAnswerCount:13},
  23.         {studentName:'任彦宇',correctRate:0,noAnswerCount:13},
  24.         {studentName:'王骁南',correctRate:0,noAnswerCount:13},
  25.         {studentName:'吴骏扬',correctRate:0,noAnswerCount:13}
  26.     ])
  27.     if (datas && datas.length > 0) {
  28.         datas.forEach((it: any, index:number) => {
  29.             knowInfo.value.push({
  30.                 '行号': index+1,
  31.                 '姓名': it.studentName,
  32.                 '正确率': it.correctRate,
  33.                 '未答题数': it.noAnswerCount
  34.             })
  35.         })
  36.         for (const key in knowInfo.value[0]) {
  37.             knowColumns.value.push({
  38.                 keyName: key,
  39.                 width: key === '行号' ? 140 : null
  40.             })
  41.         }
  42.     }
  43. }
  44.  
  45. </script>

四、其他

（1）自定义标题

  1. <el-table :data="datas" style="width: 100%;">
  2.     <el-table-column label="" prop="name" align="center">
  3.         <template #header>
  4.            姓名
  5.         </template>
  6.     </el-table-column>
  7. </el-table>

（2）自定义下标

  1. <el-table :data="datas" style="width: 100%;">
  2.     <el-table-column label="行号" align="center">
  3.         <template #default="{$index}">
  4.             {{$index+1}}
  5.         </template>
  6.     </el-table-column>
  7. </el-table>

（3）自定义内容

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

（4）添加排序（升序、降序）

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

（5）多选与单选

1. 单选

  1. <el-table :data="datas" style="width: 100%;"
  2.    row-key="id" ref="multipleTable" highlight-current-row @row-click="rowselect" @selection-change="selectGroupChange">
  3.     <el-table-column type="selection" width="55" />
  4.     <el-table-column label="排名" prop="rank" align="center"/>
  5.     <el-table-column label="时长" prop="time" align="center"/>
  6. </el-table>
  7.  
  8. <script setup lang="ts">
  9. import { ref } from "vue"
  10.  
  11. const multipleTable = ref()
  12. const handleList = ref([])
  13. // 设置单选||显示高亮
  14. const rowselect = (row:any) => {
  15.   multipleTable.value.toggleRowSelection(row)
  16. }
  17. // 选择多个单选框，只取最后选中的那一个
  18. const selectGroupChange = (row:any) => {
  19.   if (row.length > 1) {
  20.     multipleTable.value.clearSelection()
  21.     multipleTable.value.toggleRowSelection(row.pop())
  22.     return
  23.   }
  24.   if (row.length == 1) {
  25.     handleList.value = row
  26.   } else {
  27.     handleList.value = []
  28.   }
  29. }
  30. </script>
  31.  
  32. <style lang='scss' scoped>
  33. // 隐藏表头选择框
  34. :deep(.el-table__header){
  35.   .el-checkbox{
  36.     display: none;
  37.   }
  38. }
  39. </style>

2. 多选

  1. <el-table :data="datas" style="width: 100%;"
  2.    row-key="id" @select="handleSelectionChange" @select-all="handleAllChange">
  3.     <el-table-column type="selection" width="55" />
  4.     <el-table-column label="排名" prop="rank" align="center"/>
  5.     <el-table-column label="时长" prop="time" align="center"/>
  6. </el-table>
  7.  
  8. <script setup lang="ts">
  9. // 选择多个选择框
  10. const handleSelectionChange = (selecteds: any, row: any) => {}
  11.  
  12. // 全选
  13. const handleAllChange= (row:any) => {}
  14. </script>

五、实例（实现树形数据与懒加载）

示例图：通过点击当前节点，调用接口展示下一节点，实现列表的增删改查

1、添加修改组件 EditForm.vue

  1. <template>
  2.   <div>
  3.     <el-form
  4.       ref="menuEditForm"
  5.       :model="form"
  6.       :label-width="formLabelWidth"
  7.       :size="size"
  8.       :rules="rules"
  9.       clearable
  10.     >
  11.       <el-row>
  12.         <el-col :span="12">
  13.           <el-form-item label="父级字典：" prop="parentId">
  14.             <el-cascader ref="myCascader" v-model="form.parentId" :props="{ checkStrictly: true,emitPath:false,expandTrigger:'hover' }" :options="menuTree" :show-all-levels="false" placeholder="请选择父级字典" clearable />
  15.           </el-form-item>
  16.         </el-col>
  17.         <el-col :span="12">
  18.           <el-form-item label="字典名称：" :rules="rules.Required" prop="dictionaryName">
  19.             <el-input
  20.               v-model="form.dictionaryName"
  21.               autocomplete="off"
  22.               :show-word-limit="true"
  23.               placeholder="请输入字典名称"
  24.             />
  25.           </el-form-item>
  26.         </el-col>
  27.       </el-row>
  28.       <el-row v-if="title==='添加字典'">
  29.         <el-col :span="24">
  30.           <el-form-item label="字典编码：" :rules="rules.Required" prop="dictionaryCode">
  31.             <el-input
  32.               v-model="form.dictionaryCode"
  33.               autocomplete="off"
  34.               :show-word-limit="true"
  35.               placeholder="请输入字典编码"
  36.             />
  37.           </el-form-item>
  38.         </el-col>
  39.       </el-row>
  40.       <el-form-item
  41.         label="备注："
  42.         prop="remark"
  43.       >
  44.         <el-input
  45.           v-model="form.remark"
  46.           type="textarea"
  47.           maxlength="200"
  48.           :show-word-limit="true"
  49.           autocomplete="off"
  50.         />
  51.       </el-form-item>
  52.     </el-form>
  53.   </div>

  139.   }
  140. }
  141. </script>

2、主页面 index.vue

  1. <template>
  2.   <div class="app-container">
