elementui 下拉框如何传参？

Question

<el-table-column label="操作">
   <template slot-scope="scope">
      <el-dropdown trigger="click"  @command="handleCommand">
      <span class="el-dropdown-link">
        修改<i class="el-icon-arrow-down el-icon--center"></i>
      </span>
      <el-dropdown-menu slot="dropdown">
          <el-dropdown-item  command="handleEdit">编辑</el-dropdown-item>
               <el-dropdown-item  command="handleDelete">删除</el-dropdown-item>
                </el-dropdown-menu>
          </el-dropdown>
    </template>
</el-table-column>

当点击编辑的时候，需要当行的数据，这不是el-button，不能
