使用angular中的索引保存表中特定行的数据

tableData: any[] = [
  { id: 1, name: 'John', age: 25 },
  { id: 2, name: 'Jane', age: 30 },
  { id: 3, name: 'Bob', age: 35 }
];

<table>
  <tr *ngFor="let row of tableData; let i = index">
    <td>{{ row.id }}</td>
    <td>{{ row.name }}</td>
    <td>{{ row.age }}</td>
    <td>
      <button (click)="editRow(i)">Edit</button>
      <button (click)="deleteRow(i)">Delete</button>
    </td>
  </tr>
</table>

getRowData(index: number) {
  return this.tableData[index];
}

updateRowData(index: number, newData: any) {
  this.tableData[index] = newData;
}

deleteRowData(index: number) {
  this.tableData.splice(index, 1);
}
