监听el-table滚动

mounted() {
    // 监听el-table滚动
    window.addEventListener("scroll", this.loadMore, true);
  },

后端接口没有分页，一次性返回全部数据，前端监听滚动条加载数据。

this.tableList当前表格展示的数据

this.allTableData接口获取的全部数据

 loadMore() {
      let curlens = this.allTableData.length;
      let showlens = this.tableList.length; 
      if (showlens >= curlens) {
        return;
      } else {
          this.tableList.push(
            ...this.allTableData.slice(showlens, showlens + 10)
          );
      }
    },
//接口获取表格数据

 abStsLog(this.filters).then((res) => {
          this.tableList = res.data.slice(0,20);
          this.allTableData = res.data;
          this.listLoading = false;
        });
