Clickable jtable header?

[Kevin Hamrick]

So the situation is this. I build a jtable dynamically from data I grabbed out of a database. Now I want to have the header tags do a sort(sorting being another problem) when a column is clicked. I do not know how to tell which column is clicked. Here is the snippet of code which I was working on for the eventListener

private void displayTable(String[][] cells, String[] columns){
Container content = getContentPane();
missionTable = new JTable(cells, columns);
JScrollPane tablePane = new JScrollPane(missionTable);
content.add(tablePane, BorderLayout.CENTER);
setSize(450,150);
setVisible(true);
missionTable.getTableHeader().addMouseListener(new MouseAdapter(){
public void mouseClicked(MouseEvent e){
int columnID = missionTable.getSelectedColumn();
System.out.println("Clicked Column Number " + columnID);
}
});
 

}
 

The print statement returns -1 each time which means that none of the 9 columns were selected. Not sure how to do this. Please help and thanks.

I think this topic is very nicely covered in:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html

BTW, we have a forum here, which is called Swing/AWT/SWT/JFace.
