ng-repeat没有显示数据角度

Question

我有一个校园的JSON文件，需要完成房间和操作（比如修理投影仪......）

我想将操作放在表格中，但它没有显示任何内容

请参阅我的代码：

JSON文件

                }
            ]
        },

HTML

<article ng-show="selection == 'actions'">
            <h2 class="h2">Actions</h2>


                <table class="listTable "ng-repeat="a in c.rooms.actions | filter:    {roomName:campusRoom}">

                    <thead>
                    <tr>
                        <th class="colHead" scope="col" abbr="Sort">Sort</th>
                        <th class="colCol">{{a.sort}}</th>
                        <th class="edit">Edit</th>
                    </tr>
                    <tr>
                        <th class="colHead" scope="col" abbr="Description">Description</th>
                        <th class="colCol">{{a.description}}</th>
                        <th class="edit">Edit</th>
                    </tr>
                    <tr>
                        <th class="colHead" scope="col" abbr="Date">Date</th>
                        <th class="colCol">{{a.date}}</th>
                        <th class="edit">Edit</th>
                    </tr>
                    </thead>

                </table>

        </article>

C在我的html代码的头部定义并且可以访问

有人可以帮我这个吗？
