I am currently working on implementing the mat-table in my project.
I am facing an issue where I need to change the mat-icon of a button based on a click event, but I only want this change to apply to a single row in the table. At the moment, I am able to change the icon, but the change is affecting all rows instead of just one.
Does anyone have suggestions on how I can resolve this issue?
For reference, here is my StackBlitz example: Button-icon change
To effectively manage the expansion and collapse of individual rows, it is essential to incorporate a property that can handle the value for each row. I have included a property in the array object and utilized it for expanding and collapsing.
Check out the functional code here: https://stackblitz.com/edit/angular-ugxyhc-cbbtmz?file=src%2Fapp%2Ftable-column-styling-example.html
Check out this fiddle for a demonstration: https://stackblitz.com/edit/angular-ugxyhc-ri2neq?file=src%2Fapp%2Ftable-column-styling-example.ts
To add expand functionality to a table row in Angular, you need to update the PeriodicElement object to include an "isExpanded" property. Then, by toggling this property, you can track the expanded state of each element.
export interface PeriodicElement {
name: string;
position: number;
weight: number;
symbol: string;
isExpanded?: boolean; // Keep track of expanded state
}
expand(element: PeriodicElement, expanded: boolean) {
element.isExpanded = !element.isExpanded;
}
Here's the corresponding HTML code snippet:
<td mat-cell *matCellDef="let element">
<button (click)="expand(element, isExpanded)">
<mat-icon *ngIf="!element.isExpanded">expand_more</mat-icon>
<mat-icon *ngIf="element.isExpanded">chevron_right</mat-icon>
</button>
