如何查找Matable和Execute函数的索引

Question

我有一个垫子桌，它在垫子桌上显示匹配的客户记录。在Matable旁边，我有3个按钮视图，编辑和删除。html代码

 // Edit function
  editCustomer(element) {
    this.transferServiceService.setData(element.id);
    this.router.navigateByUrl('/edit');
  }
// Delete function
  deleteCustomer(element) {
    this.customer360Service.deleteCustomer(this.customerId).subscribe(
      data => {
        console.log(data);
        console.log(this.customerId);
        this.snackbar.open('Customer Deleted Successfully', 'Close', {
          duration: 3000
        });
      },
      err => {
        console.log('***', this.customerId);
        this.snackbar.open('Failed To Delete Customer', 'Close', {
          duration: 3000
        });
      }
    );
  }

    </mat-table>
    <mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator>
  </div>

我的问题是，如果有一行，那么我可以删除或编辑客户记录。但是，如果有多个行，那么我希望能够删除索引的记录，我单击

Answer 1

而不是 this.customer360Service.deleteCustomer(this.customerId)

放这个this.customer360Service.deleteCustomer(element.id)
