适配自适应行高的el-table的左边栏的各行高的获取

效果图:

vue html:

左边进度条:

<div class="track-rcol">
  <div class="track-left-list">
    <ul>
      <div v-for="(item,index) in peopleList" :key="index">
        <li :class="{first:item == 1,first3:item == 2,last:peopleList.length == index+1}" :style="{'padding-bottom':rowEleList[index]+'px'}">
          <div></div>
          <i class="node-icon"></i>
        </li>
      </div>
    </ul>
  </div>
</div>

行高自适应的table:

<el-table ref="recordTableId">
......
</el-table>
复制代码

js:

描述:
this.peopleList 是左列的状态数组
this.$refs.recordTableId.$refs['bodyWrapper'].children[0].children[1].children 获取每行的元素
this.$refs.recordTableId.$refs['bodyWrapper'].children[0].children[1].children.clientHeight 获取每行的元素的行高
this.rowEleList 保存行高的数组

复制代码

// 设置记录列表行高的列表;
    setRowEleList() {
      if (!this.peopleList || this.peopleList.length == 0 || !this.$refs.recordTableId) {
        return
      }
      try {
        this.rowEleList = [];
        const rowEleList = this.$refs.recordTableId.$refs['bodyWrapper'].children[0].children[1].children;
        for (let index = 0; index < rowEleList.length; index++) {
          this.rowEleList[index] = rowEleList[index].clientHeight;
        }
        console.log(this.rowEleList);
      } catch (error) {
        console.log(error);
      } finally {

      }
    }
