<table>
  <tr *ngFor="let row of rows">
    <td>{{ row.name }}</td>
    <td>{{ row.age }}</td>
    <td><button (click)="deleteRow(row)">删除</button></td>
  </tr>
</table>

export class DeleteRowToolComponent {
  rows: any[];

  constructor() {
    this.rows = [
      { name: 'John', age: 25 },
      { name: 'Jane', age: 30 },
      { name: 'Bob', age: 35 }
    ];
  }

  deleteRow(row: any) {
    const index = this.rows.indexOf(row);
    if (index !== -1) {
      this.rows.splice(index, 1);
    }
  }
}
