angular报错信息之Can't bind to 'ngForOf' since it isn't a known property of 'tr'. (" 
//无法绑定到“ngforof”，因为它不是“tr”的已知属性。（“

当前错误原因是没有绑定ngforof，在@ngmodule（）中添加browsermodule到imports:[]，如果它是根模块（appmodule），则为commonmodule。

解决方法

出现此问题是你的组件顺序有误，修改BrowserModule在控制器的位置

import {BrowserModule, CommonModule} from '@angular/common';
..
..
@NgModule({
  imports: [BrowserModule, / or CommonModule /],
  ..
})
