Select or deselect multiple rows with one single selection event

Question

Does anyone know how to create a JTable which can select or deselect multiple rows with one single selection event in JTable. Fore example, if the table has
row1
row2
row3
row4
row5
row6
What I need is when user select row1 or row2, both row1 and row2 should be set to be selected. Then if user press CTRL and click one of row3 or row4, both of them should be selected including the previouse selected row1 and row2.
For deselection, if row1 and row2 are selected, when users deselect one of row1 or row2, both of them should be deselected.
Hopefully someone can give me a hint.

Here is a partial solution using a JList. Only one line gets highlighted when the user makes a selection in the list. But, two lines are returned. There is a blank line between every two lines.
     private void addLineToList() {
          String a = f_one.getText();
          String b = f_two.getText();
          if (a.length() == 0) {
               Utils.showInformationMessage("Item field is empty.");
               f_one.requestFocusInWindow();
               return;
          if (b.length() == 0) {
               Utils.showInformationMessage("Match field is empty.");
               f_two.requestFocusInWindow();
               return;
          model.addElement("item: " + a);
          model.addElement("match: " + b);
          model.addElement(" ");
          int size = model.getSize();
          pairList.setSelectedIndex(size - 3);
          f_one.setText("");
          f_two.setText("");
          f_one.requestFocusInWindow();
     private void editList() {
          if (pairList.getSelectedValue().toString().equalsIgnoreCase(" ")) {
               Toolkit.getDefaultToolkit().beep();
               f_one.requestFocusInWindow();
               return;
          if (!f_one.getText().equals("")) {
               int result = JOptionPane.showConfirmDialog(this,
               "The Item field contains text. Replace the text?",
               "Flash Card Activity", JOptionPane.YES_NO_OPTION,
               OptionPane.INFORMATION_MESSAGE);
               if (result == JOptionPane.NO_OPTION) return;
          if (!f_two.getText().equals("")) {
               int result = JOptionPane.showConfirmDialog(this,
               "The Match field contains text. Replace the text?",
               "Flash Card Activity", JOptionPane.YES_NO_OPTION,
               JOptionPane.INFORMATION_MESSAGE);
               if (result == JOptionPane.NO_OPTION) return;
          String item = "";
          String match = "";
          int index = pairList.getSelectedIndex();
          String choice = model.getElementAt(index).toString();
          if (choice.startsWith("item")) {
               item = choice;
               match = model.getElementAt(index + 1).toString();
               model.remove(index);
               model.remove(index);
               model.remove(index);
          else {
               item = model.getElementAt(index - 1).toString();
               match = choice;
               model.remove(index + 1);
               model.remove(index);
               model.remove(index - 1);
          int size = model.getSize();
          if (size > 2) {
               pairList.setSelectedIndex(size - 2);
          f_one.setText(item.substring(6));
          f_two.setText(match.substring(7));
          f_one.requestFocusInWindow();
     }
