前言
有时遇到这样的需求，就是在表格里面嵌入一个表格，以及要求带有分页，这样在ElementPlus中很好实现。以下使用Vue2语法实现一个简单例子，毕竟Vue3兼容Vue2语法，若想要Vue3版本例子，简单改改就OK了。
一、示例代码
（1）/src/views/Example/InlineTable/index.vue
<template><div class="index" v-loading="elementLoading" element-loading-text="数据正在加载中..."><!-- 外层表格 --><div class="outer-table-container"><el-tablebordersize="small"row-key="id"ref="outerTableRef"height="100%"highlight-current-row:data="outerData.list":expand-row-keys="outerData.expandedKeys"@expand-change="handleOuterDataExpandChange"><el-table-column fixed prop="id" label="游戏服务器ID" width="200" align="center"><template #default="scope"><p>{{ scope.row.id }}</p></template></el-table-column><el-table-column fixed prop="id" label="玩家列表" type="expand" width="200" align="center"><template #default="scope"><div class="outer-table-container-td__playerList" v-loading="scope.row.loading"><!-- ^ 内嵌表格 --><div class="inner-table-container"><el-tablebordersize="small"row-key="id"height="100%"highlight-current-row:data="scope.row.list"><el-table-column fixed prop="id" label="玩家ID" width="200" align="center"><template #default="scope"><p>{{ scope.row.id }}</p></template></el-table-column><el-table-column prop="power" label="玩家战力" width="auto" align="center" show-overflow-tooltip><template #default="scope"><p style="text-align: left; text-indent: 10px; margin: 0; overflow: hidden; text-overflow: ellipsis; white-space: nowrap;">{{ scope.row.power }}</p></template></el-table-column><el-table-column fixed="right" label="操作" align="center" width="150"><template #default="scope"><div class="inner-table-container-td__operation"><el-row><el-col :span="24"><!-- ^ 查看详情 --><el-tooltip effect="dark" content="查看详情" placement="top" :enterable="false" :hide-after="0"><el-button size="small" type="" style="border: unset" plain circle @click="() => {log('查看详情 =>', scope.row)}"><el-icon :size="16"><View /></el-icon></el-button></el-tooltip><!-- / 查看详情 --></el-col></el-row></div></template></el-table-column></el-table></div><!-- / 内嵌表格 --><!-- ^ 内嵌分页 --><div class="inner-pagger-container"><el-paginationv-if="scope.row.total > 0"smallbackgroundv-model:current-page="scope.row.pageNumber"v-model:page-size="scope.row.pageSize":total="scope.row.total":page-sizes="[10, 20, 50, 100]"layout="total, sizes, prev, pager, next, jumper"@size-change="handleInnerTableSizeChange(scope.row)"@current-change="handleInnerTableCurrentChange(scope.row)"/></div></div></template></el-table-column><el-table-column prop="host" label="游戏服务器名称" width="auto" min-width="400" align="center" show-overflow-tooltip><template #default="scope"><p class="outer-table-container-td__name">{{ scope.row.host }}</p></template></el-table-column><el-table-column label="创建时间" width="400" align="center"><template #default="scope"><div>{{ scope.row.createTime ? scope.row.createTime : '-' }}</div></template></el-table-column></el-table></div><!-- / 外层表格 --><!-- 外层分页 --><div class="outer-pagger-container"><el-paginationsmallbackground:current-page="outerData.pageNumber":page-size="outerData.pageSize":page-sizes="[20, 30, 50, 100]":total="outerData.total"layout="total, sizes, prev, pager, next, jumper"@size-change="handleOuterTableSizeChange"@current-change="handleOuterTableCurrentChange"></el-pagination></div><!-- / 外层分页 --></div>
