el-button經常與icon搭配使用，type屬性主要用於控制其顏色，plain屬性用於控制其風格，round、circle屬性用於控制其形狀，以下是一組增刪改查的按鈕示例：

<div>
<el-button icon="el-icon-circle-plus" type="primary">添加</el-button>
<el-button round icon="el-icon-edit" type="warning">編輯</el-button>

<el-button plain round icon="el-icon-view" type="view">查看</el-button>
<el-button circle icon="el-icon-share" type="success"></el-button>
</div>
</template>

<template>
