我正在使用 PrimeNG angular 的涡轮表，我想对列宽、长度和厚度进行排序。我申请遵循代码示例，但它不起作用我不知道为什么，这是我的代码：

<p-table [value]="section" sortField="Thickness" sortMode="single" *ngFor="let section of sections">
                            <ng-template pTemplate="header">
                                <tr>
                                    <th>Quantity</th>
                                    <th>Length</th>
                                    <th>Width</th>
                                    <th [pSortableColumn]="Thickness">Thickness</th>
                                    <th>T</th>
                                    <th>B</th>
                                    <th>L</th>
                                    <th>R</th>

                        </p-table>

我向 turbo 表添加了两个属性：sortField="Thickness" sortMode="single" 但它不起作用，任何人都可以帮我解决这个问题，谢谢 http://plnkr.co/edit/vEsGORleWpf3YKBGwYDx?p=preview

这是一个使用厚度列排序的示例。

因为我不知道您是否可以根据文档仅对特定字段进行排序，所以我创建了一个自定义click事件：

<th (click)="sortByThickness(sectionIndex)">Thickness</th>

这是排序逻辑：

sortByThickness(sectionIndex) {
    const thisRef = this;
    this.sections[sectionIndex][0].Pieces.sort(function(a, b){
      return (a.Thickness - b.Thickness)*thisRef.descThicknessOrder;
    });

    // save order choice
    this.descThicknessOrder *= -1;
}

这是一个工作的Plunker

那是你需要的吗？你有任何问题吗 ？
