场景：使用element-ui组件，scope内部自定义样式导致的错位
效果图：
解决思路： template标签可理解为一个内嵌组件，宽高重新定义，可在自定义内容外层套一层盒子，让盒子占满所有空间，再使用flex让内部元素居中
实现：

1. HTML呈现

<el-table>
...
<el-table-column
    label="工单状态"
    min-width="80">
    <template slot-scope="scope">
      <div class="flex flex-align-center flex-justify-center" style="height:100%;width:100%">
        <div class="orderstatus" :class="scope.row.color">{{scope.row.orderStatus}}</div>
      </div>
    </template>
</el-table-column>
...
</el-table>

2. CSS呈现

.orderstatus{
   width: 0.66rem;
   height: 0.27rem;
   line-height: 0.27rem;
   border-radius: 0.04rem;
   border: 0.01rem solid #fff;
 }
 .blue{
   color: #3788FF;
   border: 0.01rem solid #3788FF;
   background: rgba(55,136,255,0.3);
 }
 .deepblue{
   color: #1E77F5;
   border: 0.01rem solid #1E77F5;
   background: rgba(30,119,245,0.3);
 }
 .yellow{
   color: #ED981A;
   border: 0.01rem solid #ED981A;
   background: rgba(237,152,26,0.3);
 }
 .green{
   color: #00B825;
   border: 0.01rem solid #00B825;
   background: rgba(0,184,37,0.3);
 }
 .red{
   color: #DC2E25;
   border: 0.01rem solid #DC2E25;
   background: rgba(220,46,37,0.3);
 }
.flex {
  display: flex;
}
.flex-align-center {
  align-items: center;
}
.flex-justify-center {
  justify-content: center;
}

3. js部分

async init(){
	await require().then(res=>{
		this.tableData = res.data.map(item=>{
		  switch(item.docStatus){
		    case 0:
		      item.orderStatus = '待发布'
		      item.color = 'blue'
		      break;
		    case 1:
		      item.orderStatus = '待签收'
		      item.color = 'yellow'
		      break;
		    case 2:
		      item.orderStatus = '待提审'
		      item.color = 'deepblue'
		      break;
		    case 3:
		      item.orderStatus = '已验收'
		      item.color = 'green'
		      break;
		    case 4:
		      item.orderStatus = '已拒收'
		      item.color = 'red'
		      break;
		    default:
		      item.orderStatus = '待定'
		  }
		  return item;
		})
	})
}
