public class JDataGrid

extends javax.swing.JTable

implements DataGridModelListener, javax.swing.event.UndoableEditListener

JDataGrid provides a data grid, add some features such as row header, cell attributes, cell merge and split, undo and redo support.

The DataGridModel provides model support for cell attributes, cell class, cell editable, undo support, cell merge and split and other set methods for column name and column class. It's TableModel subclass.

The ObjectCellRenderer provides the basic cell renderer for render cell attributes.
The ObjectCellEditor provides the basic cell editor.

JDataGrid provides a row header when add into JScrollPane container, and build-in Date, Number and Boolean and String and Multiple line String renderer and editor to support cell attributes and other features.

Note:
Since JDataGrid is compitable with JTable at API level, use it just replace JTable with JDataGrid.
