how to select one cell from SWT table

table.addSelectionListener(new SelectionAdapter() 
        {
            public void widgetSelected(SelectionEvent e) 
            {
                if(table.getSelectionIndex() != -1)
                {
                    System.out.println(table.getSelectionIndex());
                    TableItem item = table.getItem(table.getSelectionIndex());
                    System.out.println(item.toString());
                }
                else
                {}
            }
