Angular 2 - 刷新ngx数据表列表问题

Question

我正在研究一个Angular 2项目.我使用ngx-datatable显示用户列表:

<ngx-datatable class="material"
[rows]="rows"
[columnMode]="'force'"
[headerHeight]="40"
[footerHeight]="40"
[rowHeight]="30"
[externalPaging]="true"
[limit]="limit"
(select)='onSelect($event)'
(activate)='onActivate($event)'
[selected]="selected"
[selectionType]="'checkbox'">
<ngx-datatable-column
    [width]="30"
    [sortable]="false"
    [canAutoResize]="false"
    [draggable]="false"
    [resizeable]="false"
    [headerCheckboxable]="true"
    [checkboxable]="true">
  </ngx-datatable-column>
      <ngx-datatable-column name="Name">
        <ng-template let-value="value" ngx-datatable-cell-template>
            <div class="redNumber">{{value}}</div>
        </ng-template>
  </ngx-datatable-column>
  <ngx-datatable-column name="Title"></ngx-datatable-column>
  <ngx-datatable-column name="company"></ngx-datatable-column>
  <ngx-datatable-column name="Status" [cellClass]="getStatusClass">  
  </ngx-datatable-column>
<ngx-datatable-column name="Last connexion"></ngx-datatable-column>

当我点击触发以下SHOWALL()方法,什么也不会发生,除非我点击第二次按钮,列表被刷新,或者如果我点击一次,调整我的浏览器窗口,列表被刷新.如何能我正确刷新列表？我究竟做错了什么？在我的组件类中,我有这个:

export class M1OamRoomsListComponent{ 
    selected = [];
    public rows = [
      .... // list of users
    ];
public limit: number;

constructor(public translation: TranslationService){
    this.limit = 10;
}

getStatusClass({ row, column, value }): any {
    return {
        'disabled': value === 'Disabled',
        'enabled': value === 'Enabled'
    };
}
onSelect({ selected }) {
    console.log('Select Event', selected, this.selected);

    this.selected.splice(0, this.selected.length);
    this.selected.push(...selected);
}

onActivate(event) {
    //console.log('Activate Event', event);
}
showAll(): void {
    this.limit = this.rows.length;
}
}

我想刷新你必须做的表:

this.rows = [...this.rows]
