hii,
if you're defining SomeTableModel, already, then
global def.
private final JTextField someTextField = new JTextField();
//private JButton refreshButton = new JButton("Refresh Data");
private JTable someTable = new JTable();
private  SomeTableModel tableModel;somewhere in class definition (for jtable)
            someTextField.setText("");
            final TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(tableModel);
            someTable.setRowSorter(sorter);
            someTextField.getDocument().addDocumentListener(new DocumentListener() {
                private void searchFieldChangedUpdate(DocumentEvent evt) {
                    String text = someTextField.getText();
                    if (text.length() == 0) {
                        sorter.setRowFilter(null);
                        //someTable.clearSelection();
                    } else {
                        try {
                            sorter.setRowFilter(RowFilter.regexFilter("(?i)" + text)); // hack for ignore CaseSensitive
                            //someTable.clearSelection();
                        } catch (PatternSyntaxException pse) {
                            JOptionPane.showMessageDialog(null, "Bad regex pattern", "Bad regex pattern", JOptionPane.ERROR_MESSAGE);
                public void insertUpdate(DocumentEvent evt) {
                    searchFieldChangedUpdate(evt);
                public void removeUpdate(DocumentEvent evt) {
                    searchFieldChangedUpdate(evt);
                public void changedUpdate(DocumentEvent evt) {
                    searchFieldChangedUpdate(evt);
            }); any changes from someTextField set filter/change result from/to SomeTableModel
