elementui el-table表格展开行，对当前展开行内容修改删除，当前行默认展开

elementui el-table表格展开行，对当前展开行内容进行修改删除操作时，要当前行默认展开

方式一 上代码

  <el-table
      v-loading="listLoading" 
      :data="list"
      :row-key="getRowKeys"
      border  
      style="width: 100%"
      :expand-row-keys="expandednewarr" 
  >

根据情况使用唯一值

 getRowKeys(row) {
      return row.user.uid;
 },

接口中

 deleteItem(item, i) { 
      const data = {
        id: [item.cart_id],
      };
      batchDelete(data).then((res) => { 
        this.$message({
          message: "删除成功",
          type: "success",
        });
        this.getList();
        this.expandednewarr.push(this.list[i].user.uid);
     });
 },

方式二 上代码

  <el-table
      v-loading="listLoading" 
      :data="list"
      :row-key="getRowKeys"
      border  
      style="width: 100%"
      @expand-change="expandChange"
      :expand-row-keys="expandednewarr" 
  >

根据情况使用唯一值

 getRowKeys(row) {
      return row.user.uid;
 },

change事件改变

 expandCHange(row, expanded) {
      this.expandednewarr = [];
      expanded.map((item) => this.expandednewarr.push(item.id));
},
