angular.js - 用ng-repeat循環出一個不規則的表格遇到了問題

Question

我有一條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"}]}
]

現在我想把這些資料透過ng-repeat渲染進一個表格中，預想圖如下：

但是遇到了很多的困難，這估計是遇過的最麻煩的ng-repeat的實踐.
附上這個表格的html程式碼，方便大家清楚看到這個表格的結構：

<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>

這個循環的問題在於，teacher是獨佔幾行的，而且還得巢狀循環。所以請求大神發動一下腦筋幫我想想這個ng-repeat具體該如何實現

Answer 1

關於Teacher是否需要合併，能否用一個變數來控制？ 例如數字，大於0是需要合併，數字幾是合併的行數。

Answer 2

代碼：

<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 答案的基礎上做了小修改：

<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>
