添加循环项，滑动条到最下方

filterScrollTo() {
      const parent = document.querySelector('#quoteitemcon');
      const child = document.getElementsByClassName('quote-con');
      console.log('parent', parent, child);
      parent.scrollTo({
        top: child[child.length - 1].offsetTop,
        behavior: 'smooth'
      });
    },

 // 删除条件
    deleteQuote(index, fieldIndex) {
      this.tableColumns[index].fieldInfo.quoteRelationship.splice(
        fieldIndex,
        1
      );
      console.log(
        'index',
        index,
        fieldIndex,
        this.tableColumns[index].fieldInfo.quoteRelationship
      );
      // this.filterData.splice(index, 1);
      this.$nextTick(() => {
        this.filterScrollTo();
      });
    },
// 添加同理，也需要调
 this.$nextTick(() => {
        this.filterScrollTo();
      });

切记：同一个页面多个地方使用或者多个页面使用filterScrollTo，记得把父子组件的id名称换掉

<el-col :span="24" class="quote-item-con" id="quoteitemcon">

                      style="margin-bottom: 10px; display: block"
                      v-show="fieldOption.length > 0"
                      >引用条件</label
                    >
