Problem with coloring rows

Question

hi there,
how can i get a single row in my jtable colored? i tried out some solutions that were postet here, but they do not work for me. my problem is, that all rows get the new color although i defined it only for one row. i post some code for better understanding and maybe debugging. my jtable consists of 28 rows and 32 colums and i ONLY want row number 18 getting colored pink. any advice are welcome.
public Tabelle() {
          super("Stundenplan");
          datenmodell = new DatenModell();
          tabelle = new JTable(datenmodell);
          TableColumn column = new TableColumn();
          column = null;
          for (int i = 0; i < 32; i++) {
          column = tabelle.getColumnModel().getColumn(i);
          if (i == 0) {
          column.setPreferredWidth(100);
          column.setCellRenderer(new CenterRenderer());
          else {
          column.setPreferredWidth(50);
          column.setCellRenderer(new CenterRenderer());
          kopf.setBorder(BorderFactory.createEtchedBorder());
          tabellenBox.add(kopf);
          tabellenBox.add(tabelle.getTableHeader());
          tabellenBox.add(tabelle);
          tabellenPanel.add(tabellenBox);
          scrollpane = new JScrollPane(tabellenPanel);
          scrollpane.setPreferredSize(new Dimension(1100, 520));
          getContentPane().add(scrollpane);
that is the constructor of the jframe. the following code is my custom cell renderer:
class CenterRenderer extends DefaultTableCellRenderer {
     public Component getTableCellRendererComponent(JTable tab, Object val, boolean sel, boolean foc, int z4, int s4) {
          Component component = super.getTableCellRendererComponent(tab,val,sel,foc,z4,s4);
          ((JLabel)component).setHorizontalAlignment(SwingConstants.CENTER);
          if (z4 == 18) {
               setBackground(Color.pink);
          return component;
}

yeah, i tried it, but then there is some strange behavior. first all rows are white, but if you select row number 18 (the pink one) it becomes pink. then if you select a cell in another column, all becomes white again until you select row number 18 again.
thats not satisfying for me, so if you have a solution for that, please post it.
thanks in advance.
