element <row>标签

      <el-row :gutter="20">
        <el-col :span="8">
          <el-input class="searchInput">
              <el-button slot="append" class="el-icon-search" type="primary">el-button>
          el-input>
        el-col>

          <el-button type="primary">添加商品el-button>
        el-col>
      el-row>

input没有设置placeholder会导致对不齐 原因不详

添加之后就解决了
