Table

    <mat-table #table [dataSource]="dataSource" matSort  (matSortChange)="sortData($event)">     <ng-container matColumnDef="id">           <mat-header-cell *matHeaderCellDef > No. </mat-header-cell>           <mat-cell *matCellDef="let element">                <mat-checkbox checked='true'></mat-checkbox>           </mat-cell>     </ng-container>     <ng-container matColumnDef="unit_num">         <mat-header-cell *matHeaderCellDef  mat-sort-header="unit_num"> Unit No. </mat-header-cell>         <mat-cell *matCellDef="let element"> {{element.unit_num}} </mat-cell>     </ng-container>     <ng-container matColumnDef="unit_type">         <mat-header-cell *matHeaderCellDef mat-sort-header="unit_type"> Unit Type </mat-header-cell>         <mat-cell *matCellDef="let element"> {{element.unit_type}} </mat-cell>     </ng-container>     <ng-container matColumnDef="shares">         <mat-header-cell *matHeaderCellDef mat-sort-header="shares"> Shares </mat-header-cell>         <mat-cell *matCellDef="let element"> {{element.shares}} </mat-cell>       </ng-container>     <ng-container matColumnDef="sections">         <mat-header-cell *matHeaderCellDef>Section </mat-header-cell>         <mat-cell *matCellDef="let element"> {{element.sections.section_type}} </mat-cell>     </ng-container>     <ng-container matColumnDef="buildings">         <mat-header-cell *matHeaderCellDef >Building </mat-header-cell>         <mat-cell *matCellDef="let element"> {{element.buildings.buildingname}} </mat-cell>     </ng-container>     <ng-container matColumnDef="_id">         <mat-header-cell *matHeaderCellDef> Action </mat-header-cell>         <mat-cell *matCellDef="let element">            <button mat-button [matMenuTriggerFor]="menu"><mat-icon>more_vert</mat-icon>           </button>             <mat-menu #menu="matMenu">               <button mat-menu-item (click)="edit(element._id)">Edit</button>               <button mat-menu-item (click)="gotoFamily(element)">Go to current family</button>               <button mat-menu-item (click)="createNewFam(element)">Create new family</button>               <button mat-menu-item (click)="openDeleteDialog(element._id)">Delete</button>                           </mat-menu>         </mat-cell>     </ng-container>     <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>     <mat-row *matRowDef="let row; columns: displayedColumns; let index=index;" mat-ripple style="position:relative;" (click)="edit(row._id,$event)"></mat-row>     </mat-table>   <mat-paginator [length]="count"     [pageSize]="pageSize"     [pageSizeOptions]="pageSizeOptions"     (page)="pageSide($event)">   </mat-paginator> 

It should actually open only menu

Answer 1

I've just had the same issue and have solved it using Will's comment to the original post, adding a click handler with $event.stopPropagation to the cell as the direct parent to the button. I'll add it here as a solution in case anyone else comes here looking for the same answer.

I have a Material data table where the row has a click event to take you through to an edit mode and the last column contains a button with a delete action. Obviously you don't want to be triggering delete and edit at the same time!

Here's the structure I've used that resolves the issue:

Snippet

// Row definition containing a click event <mat-row *matRowDef="let row; columns: displayedColumns;" (click)="onEdit(row.id)"></mat-row>  // Definition for the cell containing the button <ng-container matColumnDef="buttons">     <mat-header-cell *matHeaderCellDef></mat-header-cell>     <mat-cell *matCellDef="let group" (click)="$event.stopPropagation()">         <button mat-button (click)="onDelete(group.id)">             <mat-icon>delete</mat-icon>         </button>     </mat-cell> </ng-container> 

Full Table Code

<mat-table #table [dataSource]="dataSource" matSort>     <ng-container matColumnDef="name">         <mat-header-cell *matHeaderCellDef mat-sort-header>Name</mat-header-cell>         <mat-cell *matCellDef="let group">{{ group.name }}</mat-cell>     </ng-container>     <ng-container matColumnDef="description">         <mat-header-cell *matHeaderCellDef>Description</mat-header-cell>         <mat-cell *matCellDef="let group">{{ group.description }}</mat-cell>     </ng-container>     <ng-container matColumnDef="buttons">         <mat-header-cell *matHeaderCellDef></mat-header-cell>         <mat-cell *matCellDef="let group" (click)="$event.stopPropagation()">             <button mat-button (click)="onDelete(group.id)">                 <mat-icon>delete</mat-icon>             </button>         </mat-cell>     </ng-container>      <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>     <mat-row *matRowDef="let row; columns: displayedColumns;" (click)="onEdit(row.id)"></mat-row> </mat-table>
