If you refresh the list in the component, the table refresh automatically. Example after confirm a delete operation:

import { Component } from '@angular/core';
import { Interface } from '../..//model/interface.model'
import { InterfaceService } from '../../service/interface.service'
import { ButtonModule } from 'primeng/primeng';
import { ConfirmDialogModule, ConfirmationService } from 'primeng/primeng';

@Component({
    templateUrl: './interfaces.component.html'
})
export class InterfacesComponent {

    interfaces: Interface[];

    constructor(
        private interfaceService: InterfaceService,
        private confirmationService: ConfirmationService
    ) { }

    ngOnInit() {
        this.find();
    }

    find() {
        this.interfaceService.query().then(interfaces => this.interfaces = interfaces);
    }

    confirm(id: number) {
        this.confirmationService.confirm({
            message: 'Are you sure that you want to delete this record?',
            accept: () => {
                this.interfaceService.delete(id).then((_interface) => {
                    this.find();
                });            
            }
        });
    }

}
