 * TActiveTableCellEventParameter class.

 * The TActiveTableCellEventParameter provides the parameter passed during the callback
 * requestion in the {@link getCallbackParameter CallbackParameter} property. The
 * callback response content (e.g. new HTML content) must be rendered
 * using an THtmlWriter obtained from the {@link getNewWriter NewWriter}
 * property, which returns a <b>NEW</b> instance of TCallbackResponseWriter.
 *
 * The {@link getSelectedCellIndex SelectedCellIndex} is a zero-based index of the
 * TActiveTableCell , -1 if the cell is not part of the cell collection (this shouldn't
 * happen though since an exception is thrown before).
