0303: Can't bind to 'ngIf' since it isn't a known property of 'tbody'. l

这个错误通常是因为你的组件中没有引入 `CommonModule`,请确保在你的组件中引入了 `CommonModule`。在你的组件中加入以下代码:
```typescript
import { CommonModule } from '@angular/common';
@NgModule({
imports: [
CommonModule,
// other modules
],
// ...
})
export class YourModule { }
```
如果你已经引入了 `CommonModule`,请检查你的模板中是否正确使用了 `*ngIf`,例如:
```html
<tbody *ngIf="items.length > 0">
<!-- table content -->
</tbody>
```
确保你的 `*ngIf` 使用了正确的语法,并且你的组件中正确引入了 `CommonModule`。

Can't bind to 'ngModel' since it isn't a known property of 'input'.
回答: 当出现"Can't bind to 'ngModel' since it isn't a known property of 'input'"错误时,这是因为没有在当前组件所属的模块中引用FormsModule。要解决这个问题,你需要在当前组件所属的模块中添加FormsModule的引用。具体做法是在module.ts文件中添加以下代码:import { FormsModule } from '@angular/forms';然后在imports数组中加入FormsModule。这样就可以解决"Can't bind to 'ngModel' since it isn't a known property of 'input'"错误了。\[1\]\[2\]\[3\]

Can't bind to 'formGroup' since it isn't a known property of 'form'
This error message usually occurs when the Angular form module is not imported correctly in your component or module file. To fix the error, you can follow these steps:
1. Make sure that you have imported the FormsModule or ReactiveFormsModule in your module file. For example, in your app.module.ts:
```
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms'; // Import the form modules
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule, // Add the FormsModule here
ReactiveFormsModule // Add the ReactiveFormsModule here
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
```
2. If you have already imported the form module, check if you have spelled the formGroup correctly in your component. Make sure that it is written as 'formGroup' with a capital 'G' and not 'formgroup' or 'FormGroup'.
3. Ensure that you have added the form tags correctly in your component HTML file. For example, if you are using a reactive form, your HTML code should look like this:
```
<form [formGroup]="myForm">
<!-- form controls -->
</form>
```
By following these steps, you should be able to fix the "Can't bind to 'formGroup' since it isn't a known property of 'form'" error.
