用nz-tabel寫一個合并表格

		<nz-table #basicTable [nzData]="tableSearchStatus.dataList" nzBordered><thead><tr><th>班級</th><th>姓名</th><th>年齡</th><th>電話</th></tr></thead><tbody><!-- 使用 ng-container 進行循環 --><ng-container *ngFor="let classItem of basicTable.data; let i = index"><!-- 第一行：班級名稱和第一個學生的詳細信息 --><tr *ngIf="classItem.students.length > 0"><td [attr.rowspan]="classItem.students.length">{{ classItem.className }}</td><td>{{ classItem.students[0].name }}</td><td>{{ classItem.students[0].age }}</td><td>{{ classItem.students[0].phone }}</td></tr><!-- 后續行：其余學生的詳細信息 --><tr *ngFor="let student of classItem.students.slice(1)"><td>{{ student.name }}</td><td>{{ student.age }}</td><td>{{ student.phone }}</td></tr><!-- 如果沒有學生，則單獨一行顯示班級信息 --><tr *ngIf="classItem.students.length === 0"><td>{{ classItem.className }}</td><!-- 也可以不合并  在追加兩個td --><td colspan="3">無學生信息</td></tr></ng-container></tbody></nz-table>
