vue2，vue3基于elementUI的el-table实现复制粘贴功能

vue2
vue3

1、先声明一下，为啥又有vue2和vue3呢，因为老项目要改造成vite+ts+vue3,时间紧，来不及全部转换，所以就有了componentApi和optionsApi共存的情况

2、单页面使用，全局未实现

vue2

既然是基于el-table呢就有现成的methods可以使用
@row-contextmenu="rowContextmenu"
@row-click="rowClick"

<template><el-tableref="multipleTableRef"v-loading="loading":data="state.dataList"style="width: 100%; margin-bottom: 20px"border:cell-style="cellStyle"@sort-change="sortChange":header-cell-style="headerCellStyle"@selection-change="handleSelectionChange"@row-contextmenu="rowContextmenu"@cell-mouse-leave="cellMouseLeave"@row-click="rowClick"><el-table-column  align="center" prop="status" label="是否正确" show-overflow-tooltip width="130"><template #default="{ row }"><span v-if="row.status === 1">正确</span><span v-if="row.status === 2">错误</span></template></el-table-column>
</el-table><div v-if="position.show":style="{ position: 'fixed', top: position.y + 'px', left: position.x + 'px', zIndex: 9999, display: 'flex',justifyContent:'center',alignItems:'center',flexFlow:'column',borderRadius:'5px' }"class="context-menu"><!-- 菜单内容 --><span class="posItem" @click="copyText('column')"><el-icon><DocumentCopy/></el-icon>复制当前行</span><span class="posItem" @click="copyText('row')"><el-icon><DocumentCopy/></el-icon>复制当前列</span></div>
