angular报错：
More than one component matched on this element.
Make sure that only one component's selector can match a given element.
Conflicting components: jqxGridComponent,jqxGridComponent ("ers'" [icon]="'fa-table'"></app-page-header> <div class="row"> <div class="col col-xl-6 col-lg-12"> [ERROR ->]<jqxGrid #myGrid [width]="850" [source]="dataAdapter" [showstatusbar]="true" [renderstatusbar]="creat"): ng:///UsersModule/UsersComponent.html@0:157
