vue table添加数据后设置滚动条到底部

 js
 let table = document.getElementById('id名字');
 table.scrollTop = table.scrollHeight;

  ref="listTable"
  border
  :data="adContentData"
  row-key="id"
  class="mt20"
  height="400px"
>
.....

// 添加内容
add() {
  this.contentData.push({
    adImg_big: '',
    jumpUrl: '',
    editType: true,
    sort: this.sort
  })
  this.sort++
  this.$nextTick(() => {
    this.$refs.listTable.bodyWrapper.scrollTop = this.$refs.listTable.bodyWrapper.scrollHeight;
  })
},

如果要在不同屏幕下表格高度需要适应屏幕的话，需要用到 window.onresize 函数

window.onresize = () => {
  this.height= window.innerHeight - 405;
}
