AbstractTableModel
, DefaultTableModel
public interface TableModel
TableModel
interface specifies the methods the JTable
will use to interrogate a tabular data model. The JTable
can be set up to display any data model which implements the TableModel
interface with a couple of lines of code:
TableModel myData = new MyTableModel(); JTable table = new JTable(myData);
