JTable selection listener doesn't listen to column changes

[Kevin Tysen]

  JTable standardTable = new JTable();
  standardTable.setCellSelectionEnabled(true);
  standardTable.getSelectionModel().addListSelectionListener(new ListSelect());

 public class ListSelect implements ListSelectionListener{
  public void valueChanged(ListSelectionEvent lse){
   if (!lse.getValueIsAdjusting()){
// do stuff
   }
  }
 }

This is a basic implementation of ListSelectionListener with cell selection enabled, so a single column is selected whenever a row is selected, and together the selections determine a cell selection, right?
When nothing in the cell is selected, and then a cell is selected by clicking on it, it triggers a ListSelectionEvent, as it should.
After that, when a cell in a different row on the same table is selected, it triggers an event.
However, when a cell on the same row and a different column is clicked on, or moved to by right or left arrow buttons, it does not trigger a ListSelectionEvent. I think it should change because the column selection does change even though the row selection does not.
How can I make the program listen to changes in column selection, when the row selection does not change?

Hint: a JTable's TableColumnModel has its own ListSelectionModel.

You have to add two listeners:

ListSelectListenerObj=new ListSelect()
table.getSelectionModel().addListSelectionListener(ListSelectListenerObj);
table.getColumnModel().getSelectionModel() .addListSelectionListener(ListSelectListenerObj);
