如果不是，Angular 2（v6）内联吗？

Question

I use Angular Material Tables. And display in a table a list of columns (displayedColumns).

I need to display the "birthday" column using the "date" filter ( {{element[column] | date}} ), but let other columns as is. How do I say, if the column=="birthday" then apply the filter "date"?

<ng-container matColumnDef="{{column}}" *ngFor="let column of displayedColumns">
  <th mat-header-cell *matHeaderCellDef> {{column}} </th>
  <td mat-cell *matCellDef="let element"> {{element[column]}} </td>
</ng-container>

Answer 1

Try that :

<ng-container matColumnDef="{{column}}" *ngFor="let column of displayedColumns">
  <th mat-header-cell *matHeaderCellDef> {{column}} </th>
  <td mat-cell *matCellDef="let element"> {{column === 'birthday' ? (element[column] | date) : element[column]}} </td>
</ng-container>

Answer 2

您可以创建自己的管道来检查column并适当显示element ，也可以只进行三元检查：

{{column !== "birthday" ? element[column] : element[column] | date}}
