我想在我的角度应用程序中使用材料表。我浏览了材料的官方文档以使用该表。但我在这方面遇到了几个错误。

这是我的组件代码：

<div class="container">
<div class="header">
<span style="font-size: 20px;"
  >Manage <sub style="font-size: 12px;">Brands</sub></span
>
</div>
<hr style="margin: 10px 0;" />
<button class="btn btn-primary">Add Brand</button>
<br />
<hr />

<cdk-table [dataSource]="dataSource">
<!-- Position Column -->
<ng-container cdkColumnDef="position">
  <th cdk-header-cell *cdkHeaderCellDef> No. </th>
  <td cdk-cell *cdkCellDef="let element"> {{element.position}} </td>
</ng-container>

<!-- Name Column -->
<ng-container cdkColumnDef="name">
  <th cdk-header-cell *cdkHeaderCellDef> Name </th>
  <td cdk-cell *cdkCellDef="let element"> {{element.name}} </td>
</ng-container>

<!-- Weight Column -->
<ng-container cdkColumnDef="weight">
  <th cdk-header-cell *cdkHeaderCellDef> Weight </th>
  <td cdk-cell *cdkCellDef="let element"> {{element.weight}} </td>
</ng-container>

<!-- Symbol Column -->
<ng-container cdkColumnDef="symbol">
  <th cdk-header-cell *cdkHeaderCellDef> Symbol </th>
  <td cdk-cell *cdkCellDef="let element"> {{element.symbol}} </td>
</ng-container>

<cdk-header-row *cdkHeaderRowDef="displayedColumns"></cdk-header-row>
<cdk-row *cdkRowDef="let row; columns: displayedColumns;"></cdk-row>
</cdk-table>

</div>

这是我的导入文件夹：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { HeaderComponent } from './header/header.component';

import { MatSidenavModule } from '@angular/material/sidenav';

  ],
 imports: [

  MatDividerModule,    MatCheckboxModule,    MatSidenavModule,    MatListModule,    
  DisplayModule,     CdkTableModule

  ],

 providers: [],
 bootstrap: [AppComponent]
 })
 export class AppModule { }

错误截图

 ERROR in src/app/display/brands/brands.component.html:12:3 - error NG8001: 'cdk-table' is not a 
 known element:
 1. If 'cdk-table' is an Angular component, then verify that it is part of this module.
 2. If 'cdk-table' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of 
 this component to suppress this message.

 1. If 'cdk-table' is an Angular component and it has 'dataSource' input, then verify that it is part 
 of this module.
 2. If 'cdk-table' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of 
 this component to suppress this message.
 3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

我已经导入了所有必需的模块并使用了最新的材料和角度版本。我仍然无法理解。谁能建议我如何摆脱这个错误？

请像下面这样导入 matTableModule。

import { MatTableModule } from '@angular/material/table'
