TableModel
nO constutor de JTable usado anteriormente
constrói um TableModel
assim:
nnew AbstractTableModel() {
public String getColumnName(int
col) { return
columnNames[col].toString(); }
n public int getRowCount() { return
rowData.length; }
n public int getColumnCount() { return
columnNames.length; }
n public Object getValueAt(int row, int col)
{ return rowData[row][col]; }
n public boolean isCellEditable(int row, int
col){ return true; }
public void
setValueAt(Object v, int row, int col) { rowData[row][col]=v; fireTableCellUpdated(row,
col); }
}
nCriando a customTableModel
public TableDemo() { ... JTable table = new JTable(new MyTableModel()); ... }
class MyTableModel extends AbstractTableModel {
private String[] columnNames =
...//same as before...
private Object[][] data = ...//same
as before...
