使用多个卡片显示的时候，并且要求当列数到一定数目的时候，要自动换行，el-container 布局就满足了需求了，就要用到el-row 布局做分栏处理，

代码如下

<template>
 <el-row :gutter="20" class="el-row" type="flex" >
  <el-col :span="8" v-for = "(item,index) in apps" :key="item.id" class="el-col" >
   <el-card class="el-card" :key="index" onclick="">
    <div slot="header" class="clearfix">
     <span>{{item.appname}}</span>
    </div>
    <div >
     <div class="text item">
      <div class="item_tag" >
       <span >用户标签：</span>
      </div>
      <div class="item_desr">
       <span > {{item.tag}}</span>
      </div>
     </div>
     <div class="text item">
      <div class="item_tag">
       <span>搜索标签：</span>
      </div>
      <div class="item_desr">
       {{item.seatag}}
      </div>
     </div>
     <div class="text item">
      <div class="item_tag">
       <span>短信签名：</span>
      </div>
      <div class="item_desr">
       <span>
         {{item.wxname}}
       </span>
      </div>
     </div>
     <div class="text item">
      <div class="item_tag">
       <span>客服QQ：</span>
      </div>
      <div class="item_desr">
       {{item.qq}}
      </div>
     </div>
     <div class="text item">
      <div class="item_tag">
       <span>商务合作：</span>
      </div>
      <div class="item_desr">
       {{item.buscoo}}
      </div>
     </div>
    </div>
   </el-card>
  </el-col>
  <el-col :span="8">
   <el-card class="box-card" style="min-height: 200px;" align="middle" onclick="">
    <div class="el-card__body mid">
     <el-button icon="el-icon-circle-plus" circle></el-button>
     <el-button style="margin-left: 0;color: #505458" type="text">添加APP</el-button>
    </div>
   </el-card>
  </el-col>
 </el-row>
</template>
<script>

  margin-top: -30px;
  word-break: break-all;

补充知识：vue element框架中el-row控件里按列排列失效问题的解决

最近我在使用vue的ui框架element-ui，可能是自己经验不足，遇到了很奇怪的问题，在这里特意把解决的步骤记录一下，希望能对大家有所帮助。

首先我使用的分栏间隔的布局方式，参照官网上的例子：

<el-row :gutter="20">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

<style>
 .el-row {
  margin-bottom: 20px;
  &:last-child {
   margin-bottom: 0;
  }
 }
 .el-col {
  border-radius: 4px;
 }
 .bg-purple-dark {
  background: #99a9bf;
 }
 .bg-purple {
  background: #d3dce6;
 }
 .bg-purple-light {
  background: #e5e9f2;
 }
 .grid-content {
  border-radius: 4px;
  min-height: 36px;
 }
 .row-bg {
  padding: 10px 0;
  background-color: #f9fafc;
 }
</style>

应该效果如下图：

但是我在参考例子后，代码如下：

App.vue

<template>
 <div id="app">
<el-row :gutter="20">
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
</el-row>
</div>
</template>

<script>
</script>

<style>
 .el-row {
  margin-bottom: 20px;
 }
 .el-col {
  border-radius: 14px;
 }
 .bg-purple {
  background: #d3dce6;
 }
 .grid-content {
  border-radius: 14px;
  min-height: 36px;
 }
</style>

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'//A Vue.js 2.0 UI Toolkit for Web
Vue.use(ElementUI);

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
 el: '#app',
 router,
 components: { App },
 template: '<App/>'
})

可是效果如下：

奇怪了，为何布局变成了纵向，明明row中的布局应该是按列排列的。经过排查发现自己少了这一行：import ‘element-theme-chalk';

也就是代码应该如下：

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'//A Vue.js 2.0 UI Toolkit for Web
import 'element-theme-chalk';
Vue.use(ElementUI);

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
 el: '#app',
 router,
 components: { App },
 template: '<App/>'
})

这个时候效果如下，应该是我们希望看到的，至少列生效了：

我看了一下文档，发现并没有特别指出这一行的配置，可能是我遗漏了或者其他的原因导致的，也有可能是官网没有标识出这一点。总之加上了这一行配置解决了我的问题。在这里做一个笔记，也希望能够帮助到遇到类似的问题的同学。
