I am new to material 2 and I have implemented mat table and in which I have click event on row to open dialog and there is also a menu button in last column "Action" but on clicking on button it also open dialog box instead of opening menu.
Table

<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
