Answer 1

// See How to Use Tables in tutorial. You will get one idea about Table Renderer and Editors.
// If u understand the concept, ur problem is very easy to solve by adding Editor to your column.
"You can think of the renderer as a configurable ink stamp that the table uses to stamp appropriately formatted data onto each cell. When the user starts to edit a cell's data, a cell editor takes over the cell, controlling the cell's editing behavior.
Here, While tabing thru the table row, default all cell editors are JLabels. (Not editables)
So u can make it those cells are editable JTextFields or JComboBoxes based on the column while tabbing. And you can add Listeners to that fields too. So those editable fields are called Editor Components.
// see javax.swing.DefaultCellEditor class for more description
Here i am adding my own JTextField editor to 3rd column of a table by using
mytable.getColumnModel().getColumn(2).setCellEditor(editor );
Here editor is a obj of below class. (Not complete..class)
public class JbuiEditor extends DefaultCellEditor implements // any listener {
public JbuiEditor(JTextField tField) {
super(tField);
setClickCountToStart(1);
tField.addFocusListener(this);
this.editorComponent = tField;
public Component getComponent(){
     return editorComponent;
public Component getTreeCellEditorComponent(JTree tree, Object value,
                              boolean isSelected,
                              boolean expanded,
                              boolean leaf, int row) {
     String StringValue = tree.convertValueToText(value, isSelected,
                         expanded, leaf, row, false);
     delegate.setValue(stringValue);
     return editorComponent;
public Object getCellEditorValue() {
return super.getCellEditorValue();
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected,int row, int column) {
super.getTableCellEditorComponent(table,value,isSelected,row,column);
((JTextField)editorComponent).setText(value.toString());
//Here u can add any type of listener to this Editor component.like..
((JTextField)editorComponent).addActionListener(..);
((JTextField)editorComponent).addFocusListener(..);
return editorComponent;
Hope gives some idea.
