Angular 角度-如何在模板文件中添加或使用搜索过滤器管道

我正在努力学习角度，我遇到了一个小问题。我想在我的表中添加搜索筛选器。对于表，我使用的是角度材质。我不知道或者你可以说我不知道如何在tempelate文件中使用管道过滤器。下面是我的源代码文件

filter.pipe.ts：

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'productfilter'
})
export class ProductfilterPipe implements PipeTransform {

  transform(value:any,searchTerm:any): any {
    return value.filter(function(searchelement){
      return searchelement.name.indexOf(searchTerm) > -1
    })
    
  }

}

组件1.ts：

import { Component, OnInit } from '@angular/core';
export interface PeriodicElement {
  name: string;
  position: number;
  weight: number;
  symbol: string;
}

const ELEMENT_DATA: PeriodicElement[] = [
  {position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
  {position: 2, name: 'Helium', weight: 4.0026, symbol: 'He'},
  {position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li'},
  {position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be'},
  {position: 5, name: 'Boron', weight: 10.811, symbol: 'B'},
  {position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C'},
  {position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N'},
  {position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O'},
  {position: 9, name: 'Fluorine', weight: 18.9984, symbol: 'F'},
  {position: 10, name: 'Neon', weight: 20.1797, symbol: 'Ne'},
];
@Component({
  selector: 'app-products',
  templateUrl: './products.component.html',
  styleUrls: ['./products.component.scss']
})
export class ProductsComponent implements OnInit {
  searchedResult:string="";
  constructor() { }

  ngOnInit(): void {
  }
  displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
  dataSource = ELEMENT_DATA;
}

临时文件：

  <form class="example-form">
    <mat-form-field class="example-full-width">
      <mat-label>Elements</mat-label>
      <input matInput placeholder="search element here..." [(ngModel)]="searchedResult">
    </mat-form-field>

  
<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">
  
    <!-- Position Column -->
    <ng-container matColumnDef="position">
      <th mat-header-cell *matHeaderCellDef> No. </th>
      <td mat-cell *matCellDef="let element"> {{element.position}} </td>
    </ng-container>
  
    <!-- Name Column -->
    <ng-container matColumnDef="name">
      <th mat-header-cell *matHeaderCellDef> Name </th>
      <td mat-cell *matCellDef="let element"> {{element.name}} </td>
    </ng-container>
  
    <!-- Weight Column -->
    <ng-container matColumnDef="weight">
      <th mat-header-cell *matHeaderCellDef> Weight </th>
      <td mat-cell *matCellDef="let element"> {{element.weight}} </td>
    </ng-container>
  
    <!-- Symbol Column -->
    <ng-container matColumnDef="symbol">
      <th mat-header-cell *matHeaderCellDef> Symbol </th>
      <td mat-cell *matCellDef="let element"> {{element.symbol}} </td>
    </ng-container>
  
    <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
    <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
  </table>
  
  

元素
不
{{element.position}
名称
{{element.name}
重量
{{element.weight}}
象征
{{element.symbol}

请提供我在tempelate文件中添加管道过滤器的解决方案。提前感谢
