elementui中table列内容过长，省略号+hover显示

目的：实现element-ui中table中列内容超长时，可以在列表只显示部分内容，鼠标上去hover显示全部内容。

实现：只用在column中加 :show-overflow-tooltip="true" > //el-table字体长度过长，浮动显示

效果：

代码：

<template>
<el-table
:data="tableData"
border
style=" 100%">
<el-table-column
fixed
prop="date"
label="日期"
width="300">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
