mat-progress-bar not showing inside a table when table header is sticky

How do we show or add on the table the mat progress bar? I want to show it below the table header as you can see on where the arrow on the screenshot points.

I tried adding it below <th> but it is not showing. Any idea guys ? how do we implement this one ? Thanks.

Dont worry about the code it works fine , my question only is that how to correctly palce the progress bar so that it will show below table header.

The reason why I want to attach it to the table header is that when table header is sticky you could still see the mat progress bar when you scroll.

#ts code

<table (matSortChange)="sortData($event)" mat-table [dataSource]="dataSource" matSort id="table">
        <ng-container matColumnDef={{col.matColumnDef}} *ngFor="let col of gridColumns">
          <th mat-header-cell *matHeaderCellDef cdkDrag mat-sort-header> {{col.columnHeader}} </th>
          <mat-progress-bar mode="indeterminate"></mat-progress-bar>
          <td mat-cell *matCellDef="let row">
              <span *ngIf="col.columnHeader !== 'Property Name'">
                {{(col.value(row) !== 'null')? col.value(row) : '-'}}
              </span>
              <span *ngIf="col.columnHeader === 'Property Name'">
                {{(col.value(row) !== 'null')? col.value(row) : '-'}}
                <br>
                <span >{{row.city}}, {{row.state}}</span>
              </span>
          </td>
        </ng-container>
        <tr mat-header-row *matHeaderRowDef="displayedColumns;"></tr>
        <tr mat-row *matRowDef="let row; columns: displayedColumns;" (click)="getPlaceDetails(row.propertyAccountId)"></tr>
      </table>

CodePudding user response:

Use a separate matColumnDef and mat-header-row which will have only one column and use attr.colspan to stretch the columns

isTopRow(index, item): boolean{
  return index === 0;
}
