  11.  * The AccessibleTableModelChange interface describes a change to

  12.  * the table model.  The attributes of the model change can be

  13.  * obtained by the following methods:

  14.  * <ul>

  15.  * <li> public int getType()

  16.  * <li> public int getFirstRow();

  17.  * <li> public int getLastRow();

  18.  * <li> public int getFirstColumn();

  19.  * <li> public int getLastColumn();

  20.  * </ul>

  21.  * The model change type returned by getType() will be one of:

  22.  * <ul>

  23.  * <li> INSERT - one or more rows and/or columns have been inserted

  24.  * <li> UPDATE - some of the table data has changed

  25.  * <li> DELETE - one or more rows and/or columns have been deleted

  26.  * </ul>

  27.  * The affected area of the table can be determined by the other

  28.  * four methods which specify ranges of rows and columns

  29.  *
