前言：
element-ui的表格超出部分显示省略号。
这里实际是官方有提供的属性：show-overflow-tooltip
使用：注意在哪一行需要显示省略号，就给那个表头加
<el-table :data="tableData" border style="width: 100%" :header-cell-style="{ background: '#F5F7FA' }">
<el-table-column label="操作" header-align="center" align="center">
<template slot-scope="scope">
<el-button size="mini" @click="handleEdit(scope.row)">修改</el-button>
