Is there a convenient way to use a spinner as an editor in a Swing JTable?

Question

I deal with numeric data that is often edited up or down by 0.01*Value_of_variable, so a spinner looks like a good choice compared to a usual text cell.

Jason's answer is perfect. To help others that might be looking for a Time and Date version, I've edited Jason's code to suit. Hope it helps someone as Jason's has helped me.

public static void main( String[] args ) {
    JFrame frame = new JFrame();
    JTable table = new JTable(data,columnNames);
    //table.setSurrendersFocusOnKeystroke(true);
    TableColumnModel tcm = table.getColumnModel();
    TableColumn tc = tcm.getColumn(1);
    tc.setCellEditor(new SpinnerEditor());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(table);
