列表的批量操作组件封装 + 权限 ，如何更优雅的实现呢？Vue3

<template>
   <div>
    <!-- 列表顶部的批量操作按钮组件  / 表格中的操作按钮-->

               <el-button :link="inColumn" :type="getBtnType(index)" plain :disabled="action.disabled" v-hasPermi="action.permission" @click="commandAction(action.command)">{{action.name}}</el-button>
           </el-col>
           <el-col :span="1.5" v-if="moreActionsVisible">
               <el-dropdown @command="commandAction" :size="inColumn ? 'default' : 'large'" style="line-height:inherit;vertical-align: bottom;">
                   <el-button type="primary" plain :link="inColumn">
