单击垫子表中的按钮后,我试图隐藏一行。我不知道将*ngIf
放在哪里。我尝试了ng-container
,但是它不起作用。下面是我的HTML文件。
<mat-table class="lessons-table mat-elevation-z8" [dataSource]="application">
<ng-container matColumnDef="ID">
<mat-header-cell *matHeaderCellDef>ID</mat-header-cell>
<mat-cell *matCellDef="let application">{{application.id}}</mat-cell>
</ng-container>
<ng-container matColumnDef="Name">
<mat-header-cell *matHeaderCellDef>Name</mat-header-cell>
<mat-cell *matCellDef="let application">{{application.name}}</mat-cell>
</ng-container>
<ng-container matColumnDef="ApplicationDate">
<mat-header-cell *matHeaderCellDef>Application Date</mat-header-cell>
<mat-cell *matCellDef="let application">{{application.applyDate}}</mat-cell>
</ng-container>
<ng-container matColumnDef="TrackingNumber">
<mat-header-cell *matHeaderCellDef>Tracking Number</mat-header-cell>
<mat-cell *matCellDef="let application">{{application.trackNumber}}</mat-cell>
</ng-container>
<ng-container matColumnDef="Operation">
<mat-header-cell *matHeaderCellDef>Operation</mat-header-cell>
<mat-cell *matCellDef="let application">
<button mat-raised-button color="primary" (click)="onClickGrant()">Grant</button>
<button mat-raised-button color="warn" (click)="onClickDeny()">Deny</button>
</mat-cell>
</ng-container>
<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
<mat-row *matRowDef="let row; columns: displayedColumns"></mat-row>
</mat-table>
<mat-paginator [pageSizeOptions]="[5,10,15,20]" [pageSize]="5" showFirstLastButtons></mat-paginator>

另一种方法是将类添加到mat-row
并使用CSS隐藏它。
<mat-row *matRowDef="..." [class.hidden]="YOUR_IF_HERE"></mat-row>
您也可以在Angualr Material网站上查看类似的示例: https://stackblitz.com/angular/voqbanbobpa?file=app%2Ftable-expandable-rows-example.ts

您需要通过组件代码<xarray.Dataset>
Dimensions: (month: 12)
Coordinates:
* month (month) int64 1 2 3 4 5 6 7 8 9 10 11 12
Data variables:
temp (month) float64 dask.array<shape=(12,), chunksize=(1,)>
来修改dataSource
对象,并删除要隐藏的行。
这取决于您的组件代码,但是您很可能会这样做:
