这次使用的是嵌套表格table 看官网代码之后 把官网代码改成js版 页面报错
vue.runtime.esm.js?2b0e:3049 TypeError: customRender is not a function
导致页面中table的操作栏 展示不出来 状态那一栏也展示不了 经排查 意思是customrender要展示的都没展示

代码如下

<template>
  <a-table :columns="columns" :data-source="data" class="components-table-demo-nested">
    <template #operation>
      <a>Publish</a>
    </template>
    <template #expandedRowRender>
      <a-table :columns="innerColumns" :data-source="innerData" :pagination="false">
        <template #status>
          <span>
            <a-badge status="success" />
            Finished
          </span>
        </template>
        <template #operation>
          <span class="table-operation">
            <a>Pause</a>
            <a>Stop</a>
            <a-dropdown>
              <template #overlay>
                <a-menu>
                  <a-menu-item>Action 1</a-menu-item>
                  <a-menu-item>Action 2</a-menu-item>
                </a-menu>
              </template>
              <a>
                More
                <down-outlined />
              </a>
            </a-dropdown>
          </span>
        </template>
      </a-table>
    </template>
  </a-table>

  })

export default {
  components: {
    DownOutlined
  },
  data () {
    return {
      data,
      columns,
      innerColumns,
      innerData
    }
  }
}

在网上看到这个关键词 scopedSlots
于是 把js中的slots改成全局 scopedSlots 即可
