问题不在于 TurboTable，而在于最后一列，其中每行显示 3401 行的 24 个图标。
即使在桌子外面，显示 81624 图标也需要几秒钟的时间。要说服您，请尝试以下操作：
<div *ngFor="let car of cars">
<li *ngFor="let item of sales">
<i class="fa {{item.icon}}"></i>
</li>
</div>
您将遇到相同的性能问题。
为了解决您的问题，为什么不使用分页？这将非常快：
<p-table [value]="cars" sortField="brand" [paginator]="true" [rows]="10">
...
</p-table>
