我在尝试manuallky触发器对ngx-datatable中的行进行排序时遇到了一些问题。 场景是在小型设备上我将一些列从标题移动到ngx-datatable-row-detail,但是当我尝试调用customSort函数时,ngx-datatable中的行没有被排序为我期待。

模板如下所示:

<ngx-datatable #myTable [columnMode]="'flex'"
                   [rows]="_appointments"
                   [rowHeight]="'auto'"
                   [sorts]="listProps.currentSort"
                   (sort)="sorted($event)"
                   [columns]="_tableColumns">

        <ngx-datatable-row-detail [rowHeight]="'auto'" #myDetailRow>
            <ng-template let-row="row" let-expanded="expanded" ngx-datatable-row-detail-template>
                <div class="ngx-table-toogle hidden-md">
                    <div [class.visible-xs]="myCol.collapse_xs" [class.visible-sm]="myCol.collapse_sm" *ngFor="let myCol of _collapsedTableColumns">
                        <div class="col-xs-12 col-sm-4" [class.sortable]="myCol.sortable" (click)="onCustomSort(myCol.prop,myCol.sortable)">
                            <div class="detail-row-header">
                                {{myCol.name}}
                                <span [class.sort-btn]="myCol.sortable" [class.sort-desc]="isSortedBy(myCol.prop,'desc')" [class.sort-asc]="isSortedBy(myCol.prop,'asc')"></span>
                            </div>
                        </div>
                        <div class="col-xs-12 col-sm-8">
                            <span class="detail-row-data">{{getVal(row,myCol.prop)}}</span>
                        </div>
                    </div>
                </div>
            </ng-template>
        </ngx-datatable-row-detail>

onCustomSort方法如:

 onCustomSort(sortCol: string, sortable:boolean) {
        if (!sortable)
            return;

        let curdir = this.listProps.currentSort[0].dir === SortDirection.desc ? SortDirection.asc : SortDirection.desc;
        // Hmm, doesn't trigger a resorting of the table.
        this.listProps.currentSort = [{ prop: sortCol, dir: curdir }];
        this.table.sorts = this.listProps.currentSort;

    }

我希望修改this.listProps.currentSort会触发表格,因为它绑定到[sorts]="listProps.currentSort"但没有任何反应。

有什么想法吗?

实际上解决方案非常简单,只需要添加

this.table.onColumnSort({ sorts: this.listProps.currentSort });

到onCustomSort方法,所以它现在看起来像这样:

onCustomSort(sortCol: string, sortable:boolean) {
    if (!sortable)
        return;

    let curdir = this.listProps.currentSort[0].dir === SortDirection.desc ? SortDirection.asc : SortDirection.desc;

    this.listProps.currentSort = [{ prop: sortCol, dir: curdir }];
    this.table.onColumnSort({ sorts: this.listProps.currentSort });

}
