angular - 单击按钮时如何以编程方式触发刷新 primeNG 数据表

Question

我有一个位于 primeNG 数据表之外的刷新按钮。如何以编程方式触发刷新数据表？

像这样:

<div class="pull-right">
  <button
    id="FilterBtnId"
    (click)="???">
  </button>
                </div>
<p-dataTable
   #datatable
   [value]="datasource"
   [(selection)]="jobs"
   [totalRecords]="totalRecords"
   selectionMode="multiple"
   resizableColumns="true"
   [pageLinks]="10"
   [rows]="10"
   [rowsPerPageOptions]="[10, 25, 50, 100]"
   [paginator]="true"
   [responsive]="true"
   [lazy]="true"
   (onLazyLoad)="getNewDatasource($event)"
   (onRowSelect)="onRowSelect($event)"
   >
     <p-column [style]="{'width':'40px'}" selectionMode="multiple"></p-column>
     <p-column *ngFor="let col of dt.colDefs" [field]="col.field" [header]="col.headerName" [sortable]="true">
     </p-column>
</p-dataTable>

Angular form guide包含一个可以用作解决方法的小技巧，它包括通过向元素添加 *ngIf 来重新创建 dom 以控制其可见性

visible: boolean = true;
updateVisibility(): void {
  this.visible = false;
  setTimeout(() => this.visible = true, 0);
}

<button (click)="updateVisibility()">
<p-dataTable *ngIf="visible">
