如何在角度校正中使用ng-template以获得以下错误

Question

   <p-column field="boreNumber"  [hidden]="selBoreID" header="Bore ID" 
   [sortable]="true" [filter]="false" filterMatchMode="contains" 
   filterPlaceholder="Search bore number">
<ng-template  let-col let-bore="rowData" pTemplate="body">
<button type="button" class="btn btn-link" (click)="showDetails(site.siteId)">{{bore[col.field]}}</button>                
                  </ng-template>
              </p-column>

 <p-column  field="site.siteNumber" header="Site Number" [filter]="false" filterMatchMode="contains" [sortable]="true" filterPlaceholder="Search site number">
<ng-template let-col let-bore="rowData" pTemplate="body">
  <button type="button" class="btn btn-link" (click)="showDetails(site.siteId)">{{bore[col.field]}}</button> </ng-template>
</p-column>

在我的第二栏中，ng-template无效，我的第二列又是一个对象
