由于对于vue了解不够深入，导致今天写这个组件浪费了很多时间。后来一个大神同事给我指点了一下。

想做成如图所示的样式的步骤条，使用vue elementui的steps组件做。

最简单的在组件中插入代码实现样式的方法时行不通的

<div style="height: 300px;">
  <el-steps direction="vertical" :active="1">
    <el-step title="步骤 1">
        <div>001002003 </div>
    </el-step>
    <el-step title="步骤 2"></el-step>
    <el-step title="步骤 3" description="这是一段很长很长很长的描述性文字"></el-step>
  </el-steps>
</div>

所以想了一种办法，使用左右两个div实现。不过步骤条的长度，和步骤条中显示的具体内容的位置也非常不好判断。

 <div class="approvalProcess" style="backgroung-color:background-color:#DFEBFF;" >

      <div  class='approvalProcess_left'>
        <el-steps :active="active" finish-status="success" direction="vertical">
           <el-step :title="item.label"  v-for="item in approvalProcessProject" :id="item.id">

           </el-step>
        </el-steps>
         <el-button style="margin-top: 12px;" @click="next">下一步</el-button>
      </div>

      <div class='approvalProcess_right'> 
                  <table width="100%" border="0" cellspacing="0" cellpadding="0" class="processing_content">
                         <tr>
                            <td >
                            	<div class="processing_content_detail" style="float:left;width:70%"><span class="title_tjname">申请人&nbsp;&nbsp;圆领&nbsp;&nbsp;提交了割接方案</span></div> 
                              <div class="processing_content_detail" style="float:right;"><span class="title_tjname">昨天12：:24</span> </div>
                            </td>
                          </tr>
                          
                          <tr>
                            <td>

                            	<div class="processing_content_detail" style="float:left;width:70%">
                                <div style="float:left;width: 2px;height: 20px; background:#C7D4E9;margin-left:10px;margin-right:10px"></div> 
                                <span class="title_tjname" style="color:#919FB8">同意，建议通过</span></div> 
                            </td>
                          </tr>
                          
                  </table>
          </div>

后来尝试了使用vue的插槽，建一个template的插槽。名字用description 就能进去了。我需要恶补下插槽的相关知识。

<div class="stepComponent" >
    <div class="stepsTitle">
      <div style="float:left;width:2px;height:20px; background:#219AFF;"></div> 
        审批流程及意见
    </div>
    <div class="approvalProcess" >
        <el-steps :active="active" finish-status="success" direction="vertical" >
           <el-step :title="item.label"  v-for="item in approvalProcessProject" :id="item.id">
            <template slot="description" >
             <div class="step-row" v-for="item in approvalProcessProject">
               <table width="100%" border="0" cellspacing="0" cellpadding="0" class="processing_content">
                         <tr>
                            <td style="color:#98A6BE">
                            	<div class="processing_content_detail" style="float:left;width:70%"><span >申请人&nbsp;&nbsp;<span style="color:#219AFF">圆领{{}}</span>&nbsp;&nbsp;提交了割接方案</span></div> 
                              <div class="processing_content_detail" style="float:right;"><span ><i class="el-icon-time"></i>&nbsp;&nbsp;昨天12:24</span> </div>
                            </td>
                          </tr>
                          <tr>
                            <td>
                            	<div class="processing_content_detail" style="float:left;width:70%">
                                <div style="float:left;width: 2px;height: 20px; background:#C7D4E9;margin-left:10px;margin-right:10px"></div> 
                                <span style="color:#919FB8">同意，建议通过</span></div> 
                            </td>
                          </tr>
                </table>
           </div>
         </template>

           </el-step>
        </el-steps>
         <el-button style="margin-top: 12px;" @click="next">下一步</el-button>

  </div>

</div>
</template>
<script>

export default {
   components: {
  },
  props: ['data', 'defaultActive'],
  data() {
    return {
       active: 0,
       approvalProcessProject:[
           {id:'0',label: "方案制定"},
           { id:'1',label: "割接方案会审"},
           { id:'2',label: "割接审批"},
           { id:'3',label: "审批成功"},
       ],
    };
  },
   watch: {
  },
  mounted() {
  },
  computed: {
  },
  methods: {
     next() {
        if (this.active++ > 2) this.active = 0;
      },
  }
};
</script>
<style scoped>
  .stepComponent{
      background-color:#DFEBFF;
      width: 100%-20px;
      padding: 10px 10px 10px 10px;
      margin: 10px 10px 10px 10px;
  }
  .stepsTitle{
      margin: 10px 0px  10px  10px ;
  }
  .approvalProcess{
      color: #9EADC4;
      font-size: 14px;
      /* width: 100%; */
      background:#DFEBFF;
      margin-left:20px;
      margin-right:0px;
      margin-top:10px;
  }
  .processing_content{
    background-color: #D9E5F9;
  }
  .processing_content_detail{
     margin-left: 10px;
     margin-top: 3.5px;
     margin-bottom: 3.5px;
	   width:150px;
     display:inline-block;
  }
  .step-row{
     min-width:500px;
     margin-bottom:12px;
     margin-top:12px;
  }
</style>

下面是我写好的样式

基本可以实现所需样式。

有同学问：如何把图标换成图片？
是想要这样效果吗？代码载下面

<el-steps :active="1">
  <el-step title="步骤 1">
    <template slot="icon" >
      <img src="http://img4.imgtn.bdimg.com/it/u=2480604110,4008147240&fm=26&gp=0.jpg" style="height:25x;width:25px;">
    </template>
  </el-step>
  <el-step title="步骤 2" icon="el-icon-upload">
    <template slot="icon" >
      <img src="http://img.zcool.cn/community/01bc1c5694b3e932f87574bef9bc29.png" style="height:25x;width:25px;">
    </template>
  </el-step>
  </el-step>
  <el-step title="步骤 3" icon="el-icon-picture"></el-step>
</el-steps>
</div>
