you would have to extend JLabel and implement DefaultTableModel
or extend AbstractTableModel. Preferrable the second option.

Then in the getTableCellRendererComponent method, test to see if you are in row 4 or 8...or better yet row % 4 == 0. If it is, then call setPreferredSize on that label to be the size you desire.

class CustomRenderer extends DefaultTableCellRenderer {
  public Component getTableCellRendererComponent(
                     JTable table,Object value, 
                     boolean isSelected, 
                     boolean hasFocus, 
                     int row, int column) {
       Component comp = 
                   super.getTableCellRendererComponent(
     table,value,isSelected,hasFocus,
     row,column);
       JLabel label = (JLabel)comp;
    [B]if(row % 4 == 0) [/B]
        [B]label.setPreferredSize(new Dimension(100, 30));[/B]
    [B]else[/B]
        [B]label.setPreferredSize(new Dimension(100, 20)); [/B]
       return label;                   
   }
} 

Good Luck!

JTable.setRowHeight(row, rowHeight) is another possibility.
