List within list, click on the operation of the list inside to get the value of the large list

When there are two tables, we get the data of the previous table in the second table利用子传父的方法

Subassembly

-------------结构---------------
<el-table
        data={
    
    this.data}
        tooltip-effect="light"
        border={
    
    true}

        ref="domainTable"
        on-row-click={
    
    this.onRowClick}
      >
  .........
-------------方法-------------
async onRowClick(row){
    
    
      console.log(row,'-----数据');
      let i = this.expandRowKeys.indexOf(row.id)
      if( i >= 0){
    
    
        this.$refs.domainTable.toggleRowExpansion(row, false);

        this.loading = "";
        this.$refs.domainTable.toggleRowExpansion(row, true);
        this.expandRowKeys.push(row.id);
        this.$emit('listScop', row)--------------------把当前行的数据传给父组件------------
      }
    },

parent component

 domainTable(
        :data="tableData",
        :columns="tableLabel",
        :filterWidth="250",
        :innerLabel="innerLabel",

        @listScop="listScop" -----------显示--------------
      )
          span.operation(@click="start(scopeList,scope.row)" :disabled= disabled)
            span 开启缓存
--------------在methods中写listScop事件-------------
listScop(data){
    
    
      this.scopeList = data
    },  

declared in data

 data() {
    
    
    return {
    
    
      scopeList: {
    
    },
    };
  },
