Angular ngx数据表中的ngFor

我有一个ngx数据表，它显示来自json对象的数据，其中包含行和项。 但我想向表中的输入字段添加表单验证器

我有单元格模板来显示每列的自定义字段。 我研究了在表中添加formcontrols时应该使用formarray 问题是，当为my字段的输入添加NGF时，会消失

<div [formGroup]="tableValidate">
  <prx-card>
    <prx-card-body class="prx-card-body-pya">
      <ng-container *ngIf="usersTemplate && usersTemplate.length; else loadingList">
        <ngx-datatable
          class="listview responsive"
          [rows]="usersTemplate"
          [columns]="columns"

          [rowHeight]="false"
