The basic twist would be to use the key bindings API, which will allow you to override, in most cases, the default behaviour keys on many components.
This example basically applies the same named action to the Enter and Tab keys, this makes it easy to modify their behaviour through the use of a single Action
.

new Test101();
}

EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
JTable table = new JTable();
InputMap im = table.getInputMap();
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "Action.NextCell");
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0), "Action.NextCell");
ActionMap am = table.getActionMap();
am.put("Action.NextCell", new NextCellActioin(table));
DefaultTableModel model = new DefaultTableModel(10, 10);
table.setModel(model);
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new JScrollPane(table));
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class NextCellActioin extends AbstractAction {
private JTable table;
public NextCellActioin(JTable table) {
this.table = table;
}
@Override
public void actionPerformed(ActionEvent e) {
int col = table.getSelectedColumn();
int row = table.getSelectedRow();
int colCount = table.getColumnCount();
int rowCount = table.getRowCount();
col++;
if (col >= colCount) {
col = 0;
row++;
}
if (row >= rowCount) {
row = 0;
}
table.getSelectionModel().setSelectionInterval(row, row);
table.getColumnModel().getSelectionModel().setSelectionInterval(col, col);
}
}
}
The functionality of Tab is controlled by changing the default focus behaviour through the focus manager as I recall
