As no reproducible example was provided, let's refer to a sample from the official Angular Material table documentation.
In this scenario, you have the flexibility to apply custom styles to individual cells based on specific conditions:
component.ts
import { Component, VERSION } from '@angular/core';
export interface PeriodicElement {
name: string;
position: number;
weight: number;
symbol: string;
}
const ELEMENT_DATA: PeriodicElement[] = [
{ position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H' },
{ position: 2, name: 'Helium', weight: 4.0026, symbol: 'He' },
{ position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li' },
{ position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be' },
{ position: 5, name: 'Boron', weight: 10.811, symbol: 'B' },
{ position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C' },
{ position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N' },
{ position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O' },
{ position: 9, name: 'Fluorine', weight: 18.9984, symbol: 'F' },
{ position: 10, name: 'Neon', weight: 20.1797, symbol: 'Ne' },
];
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css'],
})
export class AppComponent {
name = 'Angular ' + VERSION.major;
displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
dataSource = ELEMENT_DATA;
}
HTML template
<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">
<ng-container matColumnDef="position">
<th mat-header-cell *matHeaderCellDef>No.</th>
<td mat-cell *matCellDef="let element">{{ element.position }}</td>
</ng-container>
<ng-container matColumnDef="name">
<th mat-header-cell *matHeaderCellDef>Name</th>
<td mat-cell *matCellDef="let element">{{ element.name }}</td>
</ng-container>
<ng-container matColumnDef="weight">
<th mat-header-cell *matHeaderCellDef>Weight</th>
<td mat-cell *matCellDef="let element">{{ element.weight }}</td>
</ng-container>
<!-- Custom Styling -->
<ng-container matColumnDef="symbol">
<th mat-header-cell *matHeaderCellDef>Symbol</th>
<td
[ngStyle]="{
'background-color: element.symbol === 'pass' ? red : green'
}"
mat-cell
*matCellDef="let element">{{ element.symbol }}
</td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns"></tr>
