可编辑的JTable教程

JTable table = new JTable(new MyTableModel());
table.setEditable(true);

TableColumn column = table.getColumnModel().getColumn(0);
column.setCellEditor(new MyTableCellEditor());

public class MyTableCellEditor extends DefaultCellEditor implements TableCellEditor {
    public MyTableCellEditor() {
        super(new JTextField());
    }

    @Override
    public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
        // 返回一个可编辑的组件，例如一个JTextField
        return editorComponent;
    }

    @Override
    public Object getCellEditorValue() {
        // 返回编辑器中的值
        return editorValue;
    }
}

public void setValueAt(Object value, int row, int column) {
    data[row][column] = value;
    fireTableCellUpdated(row, column);
}
