Hello!

Successfully added the TableRowSorter to a JTable (MyTable) which is using MyTableModel (extending AbstractTableModel). I want certain cells to be colored yellow. This works when no sorting is applied, but the coloring doesn't change when hitting the JTableHeader and the same cells (same row, col) are still yellow and not where the certain values (e.g. "test") are residing now.

public class MyTable extends JTable {

    private String cellContent;
    private Object obj;
    private MyTableModel _myTableModel;
    
    public MyTable(MyTableModel myTableModel) {
        super(myTableModel);
        _myTableModel = myTableModel;
    }
    
    public Component prepareRenderer(TableCellRenderer renderer, int row, int col) {
        Component c = super.prepareRenderer(renderer, row, col);
        
        // Set beckground colors in cell according to their content.
        obj = _myTableModel.getValueAt(row, col);
        cellContent = (obj != null) ? obj.toString() : "";
        if (this.isCellSelected(row, col)) {
            // nothing to do.
        } else if (col == 2 && cellContent.equals("test")) {
            c.setBackground(new Color(255, 255, 220));
        } else {
            c.setBackground(this.getBackground());
        }
        return c;
    }
}

Table configured similarily like this:

            MyTable _table = new MyTable(new MyTableModel());
            _table.setRowSorter(new TableRowSorter<TableModel>(_table.getModel()));
            ArrayList<RowSorter.SortKey> _sortKeys = new ArrayList<RowSorter.SortKey>();
            _sortKeys.add(new RowSorter.SortKey(2, SortOrder.ASCENDING));
            _sortKeys.add(new RowSorter.SortKey(3, SortOrder.ASCENDING));
            _table.getRowSorter().setSortKeys(_sortKeys);

Any ideas how to achieve that the Renderer is updating also when the sort order is changed?

Thanks in advance!
