【Vue】data.rows与data的区别？？？

<ul >{{item.name}}</a>
    </li>
</ul>

<tr v-for="item in data.rows">
    <td>{{$index+1}}</td>
    <td style="text-align: center;">{{item.name}}</td>
    <td>{{item.role_code}}</td>
    <td>{{item.sort_id}}</td>
    <td v-if="item.disabled='0'">是</td>
    <td v-else>否</td>
    <td>
        <!--<input type="button" value="查看" @click="viewRole(item.id)">-->
        <input type="button" value="修改" @click="updateVisible(item.id)">
        <input type="button" value="权限" @click="permitVisible(item.id)">
        <input type="button" value="删除" @click="delVisible(item.id)">
    </td>
    <!-- <td :class="item.disabled? 'horde':'alliance'"></td>-->
</tr>
