element table 点击按钮 表格滚动条移动

需求场景：表格列数很多的情况下，不想拖拽滚动条查看明细，所以点击按钮直接跳转到对应的位置

代码实现：

<template><div><div class = "mytable"><el-tableid = "testTable"ref = "table":data="tableData"style="width: 700px"><el-table-columnprop="date"label="日期"fixedwidth="300"></el-table-column><el-table-columnprop="name"label="姓名"width="300"></el-table-column><el-table-columnprop="address"label="地址"></el-table-column></el-table><button id = "slide" @click = "clickSlide">slide</button></div></div></template>
<script>export default ({data(){return {dom:"",tableData: [{date: '2016-05-02',name: '王小虎',address: '上海市普陀区金沙江路 1518 弄'}, {date: '2016-05-04',name: '王小虎',address: '上海市普陀区金沙江路 1517 弄'}, {date: '2016-05-01',name: '王小虎',address: '上海市普陀区金沙江路 1519 弄'}, {date: '2016-05-03',name: '王小虎',address: '上海市普陀区金沙江路 1516 弄'}],}},mounted(){},methods:{clickSlide(){let table  = document.querySelector(".mytable .el-table__body-wrapper");console.log(table);table.scrollLeft = 300},}})
</script>
<style>
.mytable{width:500px;height:600px;overflow-x: scroll;border: 1px solid #ccc;
}
</style>
