我创建了一个结合了预先输入功能的smarttable：
<input type="text" class="form-control" ng-click="selectPerson()" ng-model="selectedPerson"
bs-options="person.firstName for person in rowCollection" placeholder="Search for person" bs-typeahead>
<table st-table="displayedCollection" st-safe-src="rowCollection" class="table table-striped">
<thead>
<tr>
<th st-sort="firstName">first name</th>
<th st-sort="lastName">last name</th>
<th st-sort="birthDate">birth date</th>
<th st-sort="balance">balance</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in displayedCollection">
<td>{{row.firstName}}</td>
<td>{{row.lastName}}</td>
<td>{{row.birthDate}}</td>
<td>{{row.balance}}</td>
<td>
<button type="button" ng-click="removeItem(row)" class="btn btn-sm btn-danger">
<i class="glyphicon glyphicon-remove-circle">
</i>
</button>
</td>
</tr>
</tbody>
</table>
目标是在搜索输入中搜索表格中的人物，选择名称然后显示在其下方的智能表格中。当我选择一个人时会发射：
$scope.selectPerson = function(){
$scope.displayedCollection = $scope.selectedPerson;
console.log($scope.displayedCollection );
}
但是，它不会显示表格中的人物。我如何修复它以便显示该人？
