angular - ngTemplate 和 ngContainer 中的 FormControl

Question

我有一个工作角度形式，在两个条件下重复模板，所以我将它移到一个公共位置并定义 ngContainer 以通过传递变量来显示值，但是在模板内部，代码无法找出形式我得到以下错误

BulkEditComponent.html:28 ERROR Error: formControlName must be used with a parent formGroup directive.  You'll want to add a formGroup
       directive and pass it an existing FormGroup instance (you can create one in your class).

模板

 <h5 mat-dialog-title>
   Edit
  </h5>
  <div mat-dialog-content class="body p-10">
    <div *ngFor="let item of keyList;let i=index" [formGroup]="editForm">

      <div class="left" *ngIf="i%2 == 0">
        <ng-container *ngTemplateOutlet="columnData;context:{item:item,group: editForm}"></ng-container>
      </div>

      <div class="right" *ngIf="i%2 == 1">
        <ng-container *ngTemplateOutlet="columnData;context:{item:item,group: editForm}"></ng-container>
      </div>

    </div>
  </div>
  <mat-dialog-actions class="align-right">
    <button mat-button mat-dialog-close>Cancel</button>
    <button mat-flat-button color="primary" (click)="formatData()">Update</button>
  </mat-dialog-actions>

  <ng-template #columnData let-item='item' ;let-formGroup="editForm">
    <div class="row p-2">
      <div class="col-md-6">
        {{getColumnName(item)}}
      </div>
      <div class="col-sm-6">
        <input type="text" class="input-field" [formControlName]="item" />
      </div>
    </div>
  </ng-template>
