vue element ui中使用table添加下拉框

table表格中使用下拉框, 用插槽的方法. 为啥放进去点击不出现下拉菜单呢

<el-table-column property="operation" width="90" label="操作">
          <template>
            <el-dropdown>
              <span class="el-dropdown-link">
                操作<i class="el-icon-arrow-down el-icon--right"></i>
              </span>
              <el-dropdown-menu slot="dropdown">
                <el-dropdown-item>黄金糕</el-dropdown-item>
                <el-dropdown-item>狮子头</el-dropdown-item>
                <el-dropdown-item>螺蛳粉</el-dropdown-item>
                <el-dropdown-item disabled>双皮奶</el-dropdown-item>
                <el-dropdown-item divided>蚵仔煎</el-dropdown-item>
              </el-dropdown-menu>
            </el-dropdown>
          </template>
        </el-table-column>

效果已经出来了,点数点击后没效果,也没报错

加个插槽

<template scope="slot-scope">
</template>

这种下拉框就直接用select就好了

<el-dropdown>
  <span class="el-dropdown-link">
    下拉菜单<i class="el-icon-arrow-down el-icon--right"></i>
  </span>
  <el-dropdown-menu slot="dropdown">
    <el-dropdown-item>黄金糕</el-dropdown-item>
    <el-dropdown-item>狮子头</el-dropdown-item>
    <el-dropdown-item>螺蛳粉</el-dropdown-item>
    <el-dropdown-item disabled>双皮奶</el-dropdown-item>
    <el-dropdown-item divided>蚵仔煎</el-dropdown-item>
  </el-dropdown-menu>
</el-dropdown>

看看文档这个 你试试用例子看看 行不行 。
你试试给 el-dropdown 加上 tigger ="click" 默认是hover触发
