由于工作的需要并鉴于网上的vue2.0中vue-cli实现全选、单选方案不合适，自己写了一个简单实用的。就短短的126行代码。

<template> <div> <table> <tr> <td><input type="checkbox" v-model="checkAll">全选({{checkedCount}})</td> <td>产品名称</td> <td>价格</td> <td>数量</td> </tr> <tr v-for="(item,$index) in lists"> <td><span v-show="checkedCount===lists.length || item.checked===true">我被选中</span><input type="checkbox" :value="item.id" v-model="checked" @click="currClick(item,$index)"></td> <td>{{item.productName}}</td> <td>{{item.price}}</td> <td>{{item.count}}</td> </tr> <tr> 总价：{{totalMoney}} </tr> </table> </div></template><script> export default{ data() { return { checked:[], totalPrice:[], lists : [ { productName:'产品1', price:'24', count:'3', id:1 }, { productName:'产品2', price:'25', count:'6', id:2 }, { productName:'产品3', price:'54', count:'7', id:3 } ] } }, computed:{ totalMoney:function(item,index){ let sum = 0; for(let i=0;i<this.totalPrice.length;i++){ sum += this.totalPrice[i]; }; return sum; }, checkAll: { get: function() { return this.checkedCount == this.lists.length; }, set: function(value){ var _this = this; if (value) { this.totalPrice = []; this.checked = this.lists.map(function(item) { item.checked = true; let total = item.price*item.count; _this.totalPrice.push(total); return item.id }) }else{ this.checked = []; this.totalPrice=[]; this.lists.forEach(function(item,index){ item.checked = false; }); } } }, checkedCount: { get: function() { return this.checked.length; } } }, methods:{ currClick:function(item,index){ var _this = this; if(typeof item.checked == 'undefined'){ this.$set(item,'checked',true); let total = item.price*item.count; this.totalPrice.push(total); console.log(this.totalPrice); }else{ item.checked = !item.checked; if(item.checked){ this.totalPrice = []; this.lists.forEach(function(item,index){ if(item.checked){ let total = item.price*item.count; _this.totalPrice.push(total); } }); }else{ this.totalPrice = []; this.lists.forEach(function(item,index){ if(item.checked){ let total = item.price*item.count; _this.totalPrice.push(total); } }); } } } } }</script><style> tr td{ width:200px; background: #eee; padding:10px 0; } </style>

效果：
