<th v-for='(value,key) in students'>{{key}}</th>

<td v-for='(value,key) in students'>{{value}}</td>
</tr>
</table>
</div>
<script>
var vm = new Vue({
el: "#app",
data: {
students:
{
name: 'Tom',
gender: 'male',
age: 18,
phone: 16314773654
},
}
})
</script>
</body>

(value,key) in 对象value是对象的值,key是对象的键(属性)
(value,key,index) in 对象value是对象的值,key是对象的键(属性),index是索引
v-for 遍历数组
(value,index) in 数组value是对象,index是索引
防止渲染错位
v-for 绑定 key
<p v-for='book in books' v-bind:key="book.id">
<input type="checkbox">
<span>Id:{{book.id}},书名：{{book.tittle}}</span>
</p>
