Question

我正在尝试使用Angular Material Table之类的链接创建带有子列的垫子表。有没有办法用角形材料台做到这一点？我可以从一列创建子列吗？请通过以下链接查看表格

旧问题，但我遇到了类似问题，并找到了此示例。角材料版本为7.3.1。可以找到完整的项目here

table-basic-example.html

<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">

  <!--- Note that these columns can be defined in any order.
        The actual rendered columns are set as a property on the row definition" -->

  <!-- Position Column -->
  <ng-container matColumnDef="position">
    <th mat-header-cell *matHeaderCellDef> No. </th>
    <td mat-cell *matCellDef="let element"> {{element.position}} </td>
