angular - 具有静态数据的 Material Design 数据表布局

Question

如何在没有数据源(静态数据)的情况下使用 Material Design 数据表布局？我在 https://material.angular.io/components/table/examples 上找不到此用例的示例.例如，我尝试了以下但没有成功。

<mat-table>
 <mat-header-row>
  <mat-header-cell>One</mat-header-cell>
  <mat-header-cell>Two</mat-header-cell>
 </mat-header-row>
 <mat-row>
  <mat-cell>aaa</mat-cell>
  <mat-cell>bbb</mat-cell>
 </mat-row>
</mat-table>

我收到以下错误:

LeistungenComponent.html:195 ERROR Error: StaticInjectorError(AppModule)[MatCell -> CdkColumnDef]: 
  StaticInjectorError(Platform: core)[MatCell -> CdkColumnDef]: 
    NullInjectorError: No provider for CdkColumnDef!

Answer 1

在你的 app.module.ts 中，添加到 providers

providers:[CdkColumnDef]

添加到导入

import { CdkColumnDef } from '@angular/cdk/table';
