Solution is (but I have a bug! see below):

public class TableView extends ViewPart {
    ...
    public void createPartControl(Composite parent) {
         top = new Composite(parent, SWT.NONE);
         top.setLayout(new FillLayout());
         createTable();
    }

    private void createTablePatients() {
         patientsViewer = new TableViewer(top, SWT....);
         ...
         this.getSite().setSelectionProvider(patientsViewer);
    }
}


public class EditorForm extends EditorPart implements ISelectionListener {

    private ISelectionListener pageSelectionListener;

    private void hookSomeSelection(IEditorSite site) {
         pageSelectionListener = new ISelectionListener() {
		public void selectionChanged(
		        	IWorkbenchPart part, 
				ISelection selection) 
		{
			someSelectionChanged(part, selection);
		}
	  };
	  site.getPage().addPostSelectionListener(pageSelectionListener);
    }
	
    protected void someSelectionChanged(
				IWorkbenchPart part,
				ISelection selection) 
    {
         /* Determine which page chaged selection & do something.*/
    }

    public void init(IEditorSite site, IEditorInput input)
         throws PartInitException 
    {
         hookSomeSelection(site);
    }
    ...
    public void dispose() {
	  if (pageSelectionListener != null) {
		IWorkbenchSite site = this.getSite();
		IEditorSite site2 = this.getEditorSite();
		IWorkbenchPage pageSite = site.getPage();
		IWorkbenchPage pageEditorSite = site2.getPage();
		
		//removePostSelectionListener(pageSelectionListener);
	   }
		
	   super.dispose();
    }
    ...
    ...
    ...
}

But I have a problem!!!

As you have noticed my dispose method isn`t working! That`s because 
variables 
site & site2 is NULL`s! Why? Actually hookSomeSelection(..) must be hooked 
at the end of createPartControl(), but at that moment this.getSite & 
this.getEditorSite() are also nulls? 

 How can I retireve them? Or maybe I have wrongly initialized Editor?
