"p-dataTable" is deprecated and therefore my solution uses the newer "p-table".

Too accomplish this you need to add your own constraint for the range filter:

First you need to add a reference to your table in your component:

@ViewChild('myTable') private _table: Table;

Use it to add a new entry to the tables filterConstraints array:

ngOnInit() {
  var _self = this;
  // this will be called from your templates onSelect event
  this._table.filterConstraints['dateRangeFilter'] = (value, filter): boolean => {
    // get the from/start value
    var s = _self.dateFilters[0].getTime();
    var e;
    // the to/end value might not be set
    // use the from/start date and add 1 day
    // or the to/end date and add 1 day
    if ( _self.dateFilters[1]) {
      e =  _self.dateFilters[1].getTime() + 86400000;
    } else {
      e = s + 86400000;
    }
    // compare it to the actual values
    return value.getTime() >= s && value.getTime() <= e;
  }
}

Add a variable to hold the start and end date values and make sure you have the FormsModule added to your module:

dateFilters: any;

In your template you need to add this variable as the model for a p-calendar. Also the onSelect event of the p-calendar needs to be set. Your template should look like the following:

<p-table #myTable [columns]="cols" [value]="data" [rows]="10">
  <ng-template pTemplate="header" let-columns>
    <tr>
      <th *ngFor="let col of columns">{{col.header}}</th>
    </tr>
    <tr>
      <th *ngFor="let col of columns" [ngSwitch]="col.field">
        <p-calendar
          [(ngModel)]="dateFilters"
          appendTo="body"
          *ngSwitchCase="'date'"
          selectionMode="range"
          [readonlyInput]="false"
          dateFormat="dd.mm.yy"
          (onSelect)="myTable.filter($event, col.field, 'dateRangeFilter')">
        </p-calendar>
      </th>
    </tr>
  </ng-template>
  <ng-template pTemplate="body" let-rowData let-columns="columns">
    <tr>
      <td *ngFor="let col of columns" [ngSwitch]="true">
        <span *ngSwitchCase="col.field === 'date'">{{rowData[col.field] | date}}</span>
        <span *ngSwitchDefault>{{rowData[col.field]}}</span>
      </td>
    </tr>
  </ng-template>
</p-table>

The data and the column definition for this example table looks like the following:

this.data = [
  { date: new Date("2018-07-12"), title: "Test1", type: "123", comment: ""},
  { date: new Date("2018-07-13"), title: "Test2", type: "123", comment: ""}
];

this.cols = [
  { field: 'date', header: 'Date'},
  { field: 'title', header: 'Title'},
  { field: 'type', header: 'Type'},
  { field: 'comment', header: 'Comment'}
];

I setup a basic example here (tested with primeNg v 6.0.1):

Hope that gets you startet.
