copied!<p>In your table model:</p> <pre><code>public void delte_raw(int raw) { if (!ls.isEmpty()) { this.fireTableRowsDeleted(raw+1, raw); // why raw+1 ??? ls.remove(raw); } } </code></pre> <p>As your table model extends from <code>AbstractTableModel</code> and looking at <a href="http://docs.oracle.com/javase/7/docs/api/javax/swing/table/AbstractTableModel.html#fireTableRowsDeleted%28int,%20int%29" rel="nofollow">fireTableRowsDeleted(int firstRow, int lastRow)</a> javadoc:</p> <blockquote> <p>Notifies all listeners that rows in the range <code>[firstRow, lastRow]</code>, inclusive, have been deleted.</p> </blockquote> <p>So it should be:</p> <pre><code>public void delte_raw(int raw) { if (!ls.isEmpty()) { ls.remove(raw); // remove the row index from the List and then fire the event fireTableRowsDeleted(raw, raw); } } </code></pre> <p><strong>Knowing the exception source:</strong> looking at <code>DefaultRowSorter.checkAgainstModel(int firstRow, int endRow)</code> implementation:</p> <pre><code>private void checkAgainstModel(int firstRow, int endRow) { if (firstRow > endRow || firstRow < 0 || endRow < 0 || firstRow > modelRowCount) { throw new IndexOutOfBoundsException("Invalid range"); } } </code></pre> <p>As you can see, calling this method with <code>[raw+1,raw]</code> range causes an <code>IndexOutOfBoundsException</code>.</p> <p><strong>Edit</strong></p> <p>As @mKorbel masterfully points out, I've totally overlooked this:</p> <pre><code>int raw = table.getSelectedRow(); // this is the index in the view model.delte_raw(raw); // convert raw in the right model index is needed </code></pre> <p>You need to convert <code>raw</code> in the right model index. Otherwise it can cause side effects since in a sorted table is most likely the selected index in the view be different than its related model's index:</p> <pre><code>int raw = table.getSelectedRow(); // this is the index in the view model.delte_raw(table.convertRowIndexToModel(raw)); // perfect </code></pre> <p>See <a href="http://docs.oracle.com/javase/7/docs/api/javax/swing/JTable.html#convertRowIndexToModel%28int%29" rel="nofollow">JTable.convertRowIndexToModel(int viewRowIndex)</a></p>
