I need split page vertically (e.g. 60%:40%) to the two areas and splitter must be draggable. So I chose PrimeNG p-splitter. Right area contains p-table with horizontal scrollbar (based on doc: part: "Horizontal and Vertical"):

<p-splitter [panelSizes]="[60,40]" [style]="{'height': '400px'}">
  <ng-template pTemplate>

    <p-table [value]="cars" [scrollable]="true" [style]="{width:'600px'}" scrollHeight="200px">
    ...
    </p-table>

  </ng-template>
  <ng-template pTemplate>
    Panel 2
  </ng-template>
</p-splitter>

Problem is that table width is bound to 600px and:

1. it is not possible to drag splitter to the right (table does not allow it)
2. when splitter is dragged to the left, table width stays 600px (so there is useless blank space between table and splitter).
