css - Angular 垫表 - 粘性标题不起作用

Question

我正在使用 Angular Material 并希望有固定的标题。我已经看到很多解决方案，但没有一个适合我。

通常它应该通过将“sticky: true”添加到“mat-h​​eader-row *matHeaderRowDef=”来工作，但对我来说不是......我检查了我的 Angular Material 和 Angular CDK 版本，它们是最新的。

html:

<mat-table #table [dataSource]="dataSource">

  <ng-container matColumnDef="fromTo">
    <mat-header-cell *matHeaderCellDef> Absender/Empfänger </mat-header-cell>
    <mat-cell *matCellDef="let entry">{{entry.customer.shownName}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="forwarder">
    <mat-header-cell *matHeaderCellDef> Spediteur </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.forwarder.shownName}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="binType">
    <mat-header-cell *matHeaderCellDef> BehälterTyp </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.bin.name}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="inboundQty">
    <mat-header-cell *matHeaderCellDef> Eingang </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.inboundQty}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="outboundQty">
    <mat-header-cell *matHeaderCellDef> Ausgang </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.outboundQty}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="comment">
    <mat-header-cell *matHeaderCellDef> Kommentar </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.comment}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="user">
    <mat-header-cell *matHeaderCellDef> Benutzer </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.user.email}} </mat-cell>
  </ng-container>

  <mat-header-row *matHeaderRowDef="displayedColumns; sticky: true"></mat-header-row>
  <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>

package.json:

  "@angular/cdk": "^7.0.0",
    "@angular/material": "^7.0.0",

知道为什么“sticky:true”对我不起作用吗？

试试这个...添加<div class="example-container><div>

<div class="example-container >
  <mat-table #table [dataSource]="dataSource">

  <ng-container matColumnDef="fromTo">
    <mat-header-cell *matHeaderCellDef> Absender/Empfänger </mat-header-cell>
    <mat-cell *matCellDef="let entry">{{entry.customer.shownName}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="forwarder">
    <mat-header-cell *matHeaderCellDef> Spediteur </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.forwarder.shownName}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="binType">
    <mat-header-cell *matHeaderCellDef> BehälterTyp </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.bin.name}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="inboundQty">
    <mat-header-cell *matHeaderCellDef> Eingang </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.inboundQty}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="outboundQty">
    <mat-header-cell *matHeaderCellDef> Ausgang </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.outboundQty}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="comment">
    <mat-header-cell *matHeaderCellDef> Kommentar </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.comment}} </mat-cell>
  </ng-container>

  <ng-container matColumnDef="user">
    <mat-header-cell *matHeaderCellDef> Benutzer </mat-header-cell>
    <mat-cell *matCellDef="let entry"> {{entry.user.email}} </mat-cell>
  </ng-container>

  <mat-header-row *matHeaderRowDef="displayedColumns; sticky: true"></mat-header-row>
  <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
  </mat-table>
</div>

添加这个 CSS

.example-container {
  height: 400px;
  overflow: auto;
}
