Angular2 Error: Unresolved Reference Issue

Within my data-table.component.ts file, I have a reference to TableSorting which is also defined in the same file.

Upon running my application, I encountered the following error in the console:

Uncaught ReferenceError: TableSorting is not defined at line 54

@Input() sorting: TableSorting;

import {
    Component,
    Output,
    Input,
    EventEmitter,
    OnChanges,
    SimpleChange, NgModule,
    NgZone
} from '@angular/core';
import { IconComponent } from '../icon';
import { CheckboxComponent, CheckboxEvent } from '../checkbox';
import { DataField, DataType, EditType } from '../../models';
import {
    SortPipe,
    NumberDelimiterPipe,
    RangePipe,
    HighlighterPipe,
    SafeHTMLPipe
} from '../../pipes';

@Component({
    selector: 'data-table',
    templateUrl: './data-table.component.html',
    styleUrls: ['./data-table.component.css']
})

@NgModule({
    declarations: [
        CheckboxComponent, IconComponent, SortPipe, Range, NumberDelimiterPipe, HighlighterPipe, SafeHTMLPipe
    ]
})
export class DataTableComponent implements OnChanges {

    public activeColor: string = '#2196f3';
    public inactiveColor: string = 'grey';

    @Input() columns: DataField[];
    public visibleColumns: DataField[];
    @Input() selectColumns: boolean = false;

    @Input() data: Object[];
    public tableData: DataWrapper[];

// The rest of the code remains unchanged

I am seeking assistance in resolving the aforementioned error that is being displayed in the console. Any help would be appreciated. Thank you.

Ensure that the TableSorting class is positioned at the beginning of the file. It must be defined before being utilized.
