我正在使用primeng datatable显示一些数据，我想将两列合并为一个<p-column>字段？

<p-table [value]="data">
  <ng-template pTemplate="header">
    <tr>
      <th>Column 1</th>
      <th>Column 2</th>
    </tr>
  </ng-template>
  <ng-template pTemplate="body" let-rowData>
    <tr>
      <td>{{rowData.column1}}</td>
      <td>{{rowData.column2}}</td>
    </tr>
  </ng-template>
  <ng-template pTemplate="footer">
    <tr>
      <td>Footer 1</td>
      <td>Footer 2</td>
    </tr>
  </ng-template>
</p-table>

<ng-template pTemplate="body" let-rowData>
  <tr>
    <td>{{rowData.column1 + ' ' + rowData.column2}}</td>
  </tr>
</ng-template>
