What is the best way to emphasize a row in an Angular Material table based on a

I am facing an issue with highlighting row colors conditionally in my code. Although there are no errors, the background color is not being applied to the rows as expected. I have a total of 5 rows with the 'riskIndex' value set to 'H'. Can anyone help me identify what might be wrong with the code below?

app.component.html

<div>
 <mat-table>
  <ng-container matColumnDef="eventType">
        <mat-header-cell *matHeaderCellDef> Event Type </mat-header-cell>
        <mat-cell *matCellDef="let element"> {{element.eventType}} </mat-cell>
      </ng-container>
      <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
      <mat-row *matRowDef="let row; columns: displayedColumns;" (click)="selectedRow(row)" [ngClass]="{ 'high': row.riskIndex === 'High'}"></mat-row>
    </mat-table>
</div>

component.css

.high {
  background-color: red;
}

Answer №1

Imagine you need to emphasize a mat-row based on a specific model property, such as highlighting rows with the status "Approved".

<tr mat-row *matRowDef="let row; columns: displayedColumns; let entry"[ngClass]="{ 'highlight': entry.status == 'Approved' }"></tr>

In the code snippet above,

highlight refers to a CSS class defined in a .css file.

.highlight{
    background: #42A948; /* green */
  }

The mentioned .css file is included in the component as shown below.

@Component({

      styleUrls: ['./expense.component.css'],

    })
