Hello Klaas2001
You can add KeyListener ,MouseListener
Suppose you have set the value of cell using setValueAt()
table.addKeyListener(this);
public void keyTyped(KeyEvent src)
String val="";
int r= table.getEditingRow();
int c= table.getEditingColumn();
val=table.getValueAt(r,c).toString();
if (r!=-1 && c!=-1)
TableCellEditor tableCellEditor = table.getCellEditor(r, c);
tableCellEditor.stopCellEditing();
table.clearSelection();
table.setValueAt(val,r,c);
public void keyReleased(KeyEvent src)
public void keyPressed(KeyEvent src)
table.addMouseListener(this);
public void mouseClicked(MouseEvent e)
public void mouseEntered(MouseEvent e)
public void mouseExited(MouseEvent e)
public void mousePressed(MouseEvent e)
public void mouseReleased(MouseEvent e)
if(e.getClickCount()>=2)//Double Click
table.clearSelection();
int r= table.getEditingRow();
int c= table.getEditingColumn();
if (r!=-1 && c!=-1)
TableCellEditor tableCellEditor = table.getCellEditor (
r,c);
tableCellEditor.stopCellEditing();
table.clearSelection();
table.setValueAt("",r,c);
}//Mouse Released
You can remove keyListener and Mouse Listener whenever You want to edit
then add it later.
Regarding handling events implement javax.swing.event.TableModelListener
table.getModel().addTableModelListener(this);
public void tableChanged(javax.swing.event.TableModelEvent source)
TableModel tabMod = (TableModel)source.getSource();
     switch (source.getType())
case TableModelEvent.UPDATE:
     break;
     }//Table Changed Method
//This method gets fired after table cell value is changed.
