如何使用angular7超链接数据表中的表列值？,angular,angular-material,Angular,Angular Material,在我的应用程序中，我获取数据表中的数据。应用程序前端正在angular7上运行。现在我希望一些列的值应该有一个链接，然后单击链接将显示一个新组件。例如： Column1 Column2 Column3 value with Link 如何使用angular7实现此场景我正在查看中的路由文档但无法将其映射到我当前的要求。如果我没弄错，您使用的是角材料数据表，不是吗如果是，请尝试以下方法： <ng-container matColumnDef="pro

在我的应用程序中，我获取数据表中的数据。应用程序前端正在angular7上运行。现在我希望一些列的值应该有一个链接，然后单击链接将显示一个新组件。例如：

Column1           Column2     Column3
value with Link

如何使用angular7实现此场景

我正在查看中的路由文档

但无法将其映射到我当前的要求。

如果我没弄错，您使用的是角材料数据表，不是吗

如果是，请尝试以下方法：

 <ng-container matColumnDef="prop">
  <mat-header-cell *matHeaderCellDef> Prop Name </mat-header-cell>
  <mat-cell *matCellDef="let element">
    <a routerLink="/your-link">{{element.prop}}</a>
  </mat-cell>
</ng-container>


道具名称
{{element.prop}}

如果我没弄错的话，您使用的是角材料数据表，不是吗

如果是，请尝试以下方法：

 <ng-container matColumnDef="prop">
  <mat-header-cell *matHeaderCellDef> Prop Name </mat-header-cell>
  <mat-cell *matCellDef="let element">
    <a routerLink="/your-link">{{element.prop}}</a>
