1、给滚动条增加监听

        this.dom = this.$refs.tableRef.bodyWrapper
        this.dom.scrollTop = 0
        let _that = this
        this.dom.addEventListener('scroll', () => {
          //获取元素的滚动距离
          let scrollTop = _that.dom.scrollTop
          //获取元素可视区域的高度
          let clientHeight = this.dom.clientHeight
          //获取元素滚动条的高度
          let scrollHeight = this.dom.scrollHeight

          if (scrollTop + clientHeight == scrollHeight) {
            //不是获取全部数据，而是加载新的数据
          }
          console.log(`scrollTop:  ${scrollTop}`)
          console.log(`clientHeight:  ${clientHeight}`)
          console.log(`scrollHeight:  ${scrollHeight}`)
        })

2、滚动条滑动到指定为止

只需要给scrollTop 赋值就行了

//滚动条滑动到指定位置
this.dom.scrollTop = this.dom.scrollHeight + 300
