It takes care of the management of listeners and provides some conveniences for generating <code>TableModelEvents</code> and dispatching them to the listeners. To create a concrete <code>TableModel</code> as a sublcass of <code>AbstractTableModel</code> you need only provide implementations for the following three methods: <pre> public int getRowCount(); public int getColumnCount(); public Object getValueAt(int row, int column); </pre> <p> <strong>Warning:</strong> Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.<P><DL><DT><B>See Also: </B><DD><A HREF="../../../serialized-form.html#javax.swing.table.AbstractTableModel">Serialized Form</A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../../javax/swing/event/EventListenerList.html">EventListenerList</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#listenerList">listenerList</A></B></CODE><BR> List of listeners</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#AbstractTableModel()">AbstractTableModel</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#addTableModelListener(javax.swing.event.TableModelListener)">addTableModelListener</A></B>(<A HREF="../../../javax/swing/event/TableModelListener.html">TableModelListener</A> l)</CODE><BR> Adds a listener to the list that's notified each time a change to the data model occurs.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#findColumn(java.lang.String)">findColumn</A></B>(<A HREF="../../../java/lang/String.html">String</A> columnName)</CODE><BR> Returns a column given its name.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#fireTableCellUpdated(int, int)">fireTableCellUpdated</A></B>(int row, int column)</CODE><BR> Notifies all listeners that the value of the cell at <code>[row, column]</code> has been updated.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#fireTableChanged(javax.swing.event.TableModelEvent)">fireTableChanged</A></B>(<A HREF="../../../javax/swing/event/TableModelEvent.html">TableModelEvent</A> e)</CODE><BR> Forwards the given notification event to all <code>TableModelListeners</code> that registered themselves as listeners for this table model.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#fireTableDataChanged()">fireTableDataChanged</A></B>()</CODE><BR> Notifies all listeners that all cell values in the table's rows may have changed.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#fireTableRowsDeleted(int, int)">fireTableRowsDeleted</A></B>(int firstRow, int lastRow)</CODE><BR> Notifies all listeners that rows in the range <code>[firstRow, lastRow]</code>, inclusive, have been deleted.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#fireTableRowsInserted(int, int)">fireTableRowsInserted</A></B>(int firstRow, int lastRow)</CODE><BR> Notifies all listeners that rows in the range <code>[firstRow, lastRow]</code>, inclusive, have been inserted.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/table/AbstractTableModel.html#fireTableRowsUpdated(int, int)">fireTableRowsUpdated</A></B>(int firstRow, int lastRow)</CODE>⌨️ 快捷键说明
