element-ui表格实现全选和多选功能，先看效果图：

代码也是相对简单，根据官网提供的API来实现，具体代码奉上：

<template>
    <div>
        <el-table
            :data="tableData"
            border
            style="width: 100%">
            <el-table-column prop="date" label="日期"></el-table-column>
            <el-table-column prop="name" label="姓名"></el-table-column>
            <el-table-column prop="address" label="地址"></el-table-column>
            <el-table-column label="选择">
                <template slot-scope="scope">
                    <el-checkbox-group v-model="checkedCities" @change="handleCheckedCitiesChange">
                        <el-checkbox :label="scope.row.gameId">选中</el-checkbox>
                    </el-checkbox-group>
                </template>
            </el-table-column>
        </el-table>
        <div style="margin-top: 20px">
            <el-checkbox :indeterminate="isIndeterminate" v-model="checkAll" @change="handleCheckAllChange">全选</el-checkbox>
        </div>
    </div>
</template>
