[vtkusers] Cannot open include file: 'QObject'

I just wrote some code to display the data in the table and it works. There
is data in the table. It looks like the following code segment does not work
as I expected. Also, a table shows up but it disappears quickly.

  VTK_CREATE(vtkQtTableView, tableView);
  tableView->SetSplitMultiComponentColumns(true);
  tableView->AddRepresentationFromInput(table); //check here
  tableView->Update();
  tableView->GetWidget()->show();
