我想选择/取消选择所有复选框。我尝试引用其他代码，但对我没有任何帮助。为组选择和取消选择工作正常如何在 TurboTable 中实现个人选择功能

.html

<p-table [value]="cars" sortField="brand" sortMode="single" (onSort)="onSort()" dataKey="vin"> 
    <ng-template pTemplate="header">
        <tr>
            <th>Vin</th>
            <th>Year</th>
            <th>Color</th>
        </tr>
    </ng-template>
    <ng-template pTemplate="body" let-rowData let-rowIndex="rowIndex">
        <tr class="ui-widget-header" *ngIf="rowGroupMetadata[rowData.brand].index === rowIndex">
         <td>
                <p-tableCheckbox [value]="rowData"></p-tableCheckbox>
            </td>
            <td></td>
            <td>
                <span style="font-weight:bold">{{rowData.brand}}</span>
            </td>                
        </tr>
        <tr>
            <td><p-tableCheckbox [value]="rowData"></p-tableCheckbox></td>
            <td>{{rowData.year}}</td>
            <td>{{rowData.color}}</td>
        </tr>
    </ng-template>
</p-table>

.ts

cars: Car[];

this.cars=[
        {"vin":"a1653d4d","brand":"VW","year":1998,"color":"White","price":10000},
        {"vin":"ddeb9b10","brand":"Mercedes","year":1985,"color":"Green","price":25000},

        {"vin":"ec229a92","brand":"Audi","year":1984,"color":"Brown","price":36000},
        {"vin":"1083ee40","brand":"VW","year":1984,"color":"Silver","price":215000},
