在这里回答：
cdkHeaderCellDef 和 cdkCellDef 是 @angular/cdk 库的一部分并导出到 CdkTableModule。
在您应用的导入中包含此模块
在您的 app.module.ts 文件中导入 CdkTableModule
import { CdkTableModule } from '@angular/cdk';
并将 CdkTableModule 添加到导入中
imports: [
BrowserModule,
BrowserAnimationsModule,
FormsModule,
HttpModule,
CdkTableModule,
MaterialModule
]
在我的例子中，我从 angular 开始，我有一个类似的错误，使用 2.0.0-beta.12 版本 [=31] =]，您页面的文档 (material.angular.io/components/table/examples ) 使用前缀 "md"，在这个新版本中已被删除（现在 mat), 在这里你可以看到上述变化的注释
