angular.js - 用ng-repeat循环出一个不规则的表格遇到了问题

Question

我有一条json如下：

[
{"teacher":"Tom","student":[{"name":"stuA","project":"projectA"},{"name":"stuB","project":"projectB"}]},
{"teacher":"Jerry","student":[{"name":"stuC","project":"projectC"},{"name":"stuD","project":"projectD"},{"name":"stuE","project":"projectE"}]},
{"teacher":"Lee","student":[{"name":"stuF","project":"projectF"}]}
]

现在我想把这些数据通过ng-repeat渲染进一个表格中，预想图如下：

但是遇到了很多的困难，这估计是遇过的最麻烦的ng-repeat的实践.
附上这个表格的html代码，方便大家清楚地看到这个表格的结构：

<tr style="height:40px" >
        <td rowspan="2" style="text-align:center;background:#FFD4D4;font-weight:bold;">Tom</td>

            <td style="text-align:center;font-size:15px;font-weight:bold;">stuA</td>
            <td style="text-align:left;padding-left:100px;font-size:15px;font-weight:bold;">projectA</td>
         </tr>
   <tr style="height:40px;">
       <td style="text-align:center;font-size:15px;font-weight:bold;">stuB</td>
       <td style="text-align:left;padding-left:100px;font-size:15px;font-weight:bold;">projectB</td>
   </tr>

<tr style="height:40px">
    <td rowspan="3" style="text-align:center;background:#FFD4D4;font-weight:bold;">Jerry</td>
    <td style="text-align:center;font-size:15px;font-weight:bold;">stuC</td>
    <td style="text-align:left;padding-left:100px;font-size:15px;font-weight:bold;">projectC</td>
</tr>
<tr style="height:40px;">
    <td style="text-align:center;font-size:15px;font-weight:bold;">stuD</td>
    <td style="text-align:left;padding-left:100px;font-size:15px;font-weight:bold;">projectD</td>
</tr>
<tr style="height:40px;">
    <td rowspan="1" style="text-align:center;background:#FFD4D4;font-weight:bold;">Lin</td>
    <td style="text-align:center;font-size:15px;font-weight:bold;">stuE</td>
    <td style="text-align:left;padding-left:100px;font-size:15px;font-weight:bold;">projectE</td>
</tr>

这个循环的问题在于，teacher是独占几行的，而且还得嵌套循环。所以请求大神发动一下脑筋帮我想想这个ng-repeat具体该如何实现

Answer 1

Mengenai sama ada Guru perlu digabungkan, bolehkah ia dikawal dengan pembolehubah? Sebagai contoh, jika nombor lebih besar daripada 0, ia perlu digabungkan, dan jika nombor lebih besar daripada 0, ia bermakna bilangan baris yang akan digabungkan.

Kod:

<table class="table table-bordered">
    <thead>
        <tr>
            <th>teacher</th>
            <th>student</th>
            <th>project</th>
        </tr>
    </thead>
    <tbody ng-repeat="teacher in teachers">
        <tr ng-repeat="student in teacher.student track by $index">
            <td ng-if="$index ==0" rowspan="{{teacher.student.length}}">
                <span ng-bind="student.name"></span>
            </td>
            <td><span ng-bind="student.project"></span>
            </td>
        </tr>
    </tbody>
</table>
