<template>
J是第一遍便利的陣列
<div v-for="(j, index) in arr" :key="index" style="width: 98%; margin-left: 1%">
<div style="height: 50px" @click="DIANJI(index)">{{ j.data }}</div>
<div>
<n-table :bordered="true" :single-line="false" style="margin-bottom: 1%">
<thead>
<tr style="margin-top: 50px">
<th>序號</th>
<th width="50%">停車場</th>
<th>今日交易額</th>
<th>今日交易筆數</th>
</tr>
</thead>
<tbody>
這裡面就需要用J.陣列去便利下一個陣列，拿到裡面的內容
<tr v-show="activeIndex===index" v-for="(i, index) in j.state" :key="index">
<td>{{ i.Identifier }}</td>
<td>{{ i.paring }}</td>
<td>{{ i.Monkey }}</td>
<td :class="a">{{ i.Number }}</td>
</tr>
<tr>
<td></td>
<td>總計</td>
<td>{{ j.sumMonkey }}</td>
<td>{{ j.sumNumber }}</td>
</tr>
</tbody>
</n-table>
</div>
</div>
