vue3的通用表格我也封装了，是下面链接喔~ 

TS + vue3.2 + vite2 + element-plus 通用表格组件封装

1、父组件调用方式：

        <common-table
          show-index
          show-check-box
          :loading="loading"
          :table-label="tableHeaderData"
          :data="tableData"
          :option="tableOptionsData"
          @operation="operationHandler"
          @handle-selection-change="handleSelectionChange"
        >
          <template slot="expand" slot-scope="{ row }">
            <making-status v-if="row.status === 1" :list="row.processList || []" />
            <div v-else class="making-status-none">
              <span>未制作</span>
            </div>
          </template>
        </common-table>

2、参数详解： 

其实我定义的参数还蛮多的，基本能够把常用的功能包含进去了，我着重讲几个：

1、tableLabel：表格头部标题

有以下四个参数，最重要的是render，他的参数是从slot-scope抛出，可以进行判断显示

    {
      label: '制作格式',
      prop: 'handleType',
      width: 150,
      render(row) {
        return `<span>${row.handleType === 1 ? '查题格式' : (row.handleType === 2 ? '拍题格式' : '未设置')}</span>`
      }
    }

2、showCheckBox： 显示复选框

与之对应的回调函数是 @handle-selection-change，我们可以从中取得当前选中的复选框数组

3、showExpand： 拓展插槽

在 slot="expand" 即可以使用

        <template slot="expand" slot-scope="{ row }">
            // xxx
        </template>

4、showIndex： 是否展示序号

这里序号不是你自己的自定义id喔~是当前数组索引值 + 1

5、option： 配置需要显示的操作菜单

{
    label: '操作',
    width: '300',
    fixed: 'right',
    children: [
      {
        label: '查看制作详情',
        icon: 'el-icon-view',
        methods: 'view',
        permission: 'xxx',
        render(row) {
          return row.status !== 0
        }
      },
      {
        type: 'drop',
        icon: 'el-icon-paperclip',
        permission: 'xxx',
        children: [
          {
            label: '切题查看模式',
            methods: '1'
          },
          {
            label: '编题查看模式',
            methods: '2'
          }
        ]
      }
    ]
  }

我们主要看children里的，主要参数有4个

label： 显示名字

icon： 显示图标

permission： 即v-permission，根据按钮是否有权限再进行展示，可为字符也可为数组，这种自定义指令我就不单独写出来了，可以参考我博客，链接如下

vue学习（6）自定义指令详解及常见自定义指令，里面有个checkPermission函数，所有判断你皆可自行定义

type： 为drop 则相当于 el-dropdown，把很多按钮收缩在一起

render： 这个和上面tableLabel不一样的是，这里render返回值为true或false来决定v-show的值（只在type不为drop生效）
methods： 点击后回调触发的方法，由 @operation={row, type} 抛出，type即为methods对应值（只在type不为drop生效）

children： drop展示子数组（label和methods与上面一致）（在type为drop生效）

3、组件源码 ：

<template>
  <div v-loading="loading">
    <el-table
      ref="commonTable"
      :data="data"
      border
