简洁风格的步骤条  设置 simple 可应用简洁风格，该条件下 align-center / description / direction / space 都将失效。

针对该情况，将简单的步骤条修改为简洁风格步骤条呈现

 <el-steps 
   :active="orderActive"  
   v-if="progresses.length > 0"  
   class="el-steps-sn reset-steps">
     <el-step 
       :title="item.title" 
       :description="item.date" 
       icon="el-icon-info"  
       v-for="(item,index) in progresses" 
       :key="index">
     </el-step>
 </el-steps>

    .el-step__line-inner {

        width: 1px;

      }
      &:before {
        -webkit-transform: rotate(-45deg) translateY(-4px);
        transform: rotate(-45deg) translateY(-4px);
        -webkit-transform-origin: 0 0;
        transform-origin: 0 0;
      }
      &:after {
        -webkit-transform: rotate(45deg) translateY(4px);
        transform: rotate(45deg) translateY(4px);
        -webkit-transform-origin: 100% 100%;
        transform-origin: 100% 100%;
      }
    }
  }
  .el-step__main {
    .el-step__description.is-process,
    .el-step__description.is-finish,
    .el-step__description.is-wait {
      text-indent: 15px;
    }
  }
  .el-step__icon{background-color:transparent}
}

效果如下图：
