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

关于Teacher是否需要合并，能否用一个变量来控制？ 比如数字，大于0是需要合并，数字几是合并的行数。

Answer 2

代码：

<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>

Answer 3

在@晨末 答案的基础上做了小修改：

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