如何将多个ngif应用于表格上的数据显示？

<table>
  <tr *ngFor="let item of data; let i = index">
    <td *ngIf="condition1">...</td>
    <td *ngIf="condition2">...</td>
    <td *ngIf="condition3">...</td>
    ...
  </tr>
</table>

export class YourComponent {
  data: any[] = [...]; // 表格数据
  condition1: boolean = true;
  condition2: boolean = false;
  condition3: boolean = true;

  // 或者使用方法返回布尔值
  // condition1(): boolean {
  //   return ...;
  // }
}

// 在组件中的某个方法或事件中修改条件变量的值
toggleCondition1() {
  this.condition1 = !this.condition1;
}

<button (click)="toggleCondition1()">Toggle Condition 1</button>
