public class JGrid

extends JComponent

implements Scrollable, CellEditorListener, GridModelListener

The JGrid is used to display and edit regular two-dimensional grid of cells. Unlike JTable which is fundamentally vertical in that the structure is determined in the columns, while the rows contain the data. JGrid is symmetrical with respect to the vertical and the horizontal orientations. JGrid also allows for cells to be merged into bigger rectangular arrays, called spans.
