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
