Struggling to understand the missing piece needed for properly importing into Angular modules. Any guidance would be appreciated

Is it advisable to include PrimeNg references in multiple modules or should they be centralized in a shared module? What is the recommended practice in this scenario? I am encountering issues with importing "p-dataTable" from primeng even though it is included in the module where the component is declared.

The error message I am receiving is related to my HTML code in validation.component.html:

errors.ts:42 ERROR Error: Uncaught (in promise): Error: Template parse errors:
Can't bind to 'value' since it isn't a known property of 'p-dataTable'.
1. If 'p-dataTable' is an Angular component and it has 'value' input, then verify that it is part of this module.
2. If 'p-dataTable' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the @NgModule.schemas' of this component. ("
<body>
    <h3>Validation tabs go here.</h3>
    <p-dataTable [ERROR ->][value]="validationsList" selectionMode="single" [(selection)]="selectedValidation" dataKey="id"
    "): ng:///app/validation/validation.component.html@7:17

I have a file named validation.module.ts

} from 'primeng/primeng';

@NgModule({
imports: [

    RouterModule.forChild([

                    component: SampleIdsTableComponent

                {

                    component: RunStatusComponent
                }
            ]

        },

    SampleIdsTableComponent,
    AllTestsComponent,
    RunStatusComponent
],
providers: [

})
export class ValidationModule { }

Counting brackets can be crucial! I made the mistake of adding my imports to the RouterModule.forChild([...]) instead of the imports array.
