Dynamically colouring jTable row

Question

In the answer to my previous question, Coloring jTable row, but now I'm unsure as to new question goes here, setting color to row is working. But I want to give it from a for loop, means I want to set color for i'th row. I'm giving the which I have used,

for(int i=0;i<serialNumber;i++){
  if((jTable1.getValueAt(i,1).toString()).equals(BidNumber)){
   Enumeration<TableColumn> en = jTable1.getColumnModel().getColumns();
    while (en.hasMoreElements()) {
        TableColumn tc = en.nextElement();

        tc.setCellRenderer(new MyTableCellRenderer());
    }
}

It will invoke the method cellrenderer,

public class MyTableCellRenderer extends DefaultTableCellRenderer implements TableCellRenderer {

        @Override
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            setBackground(null);
            super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);

              boolean interestingRow = row ==1;



            if (interestingRow) {
                setBackground(Color.YELLOW);
            }

            return this;
        }

    }

here I am trying to put color for the row when first column value is equal to the BidNumber, but in cellrenderer(here),it's set as row==1,then every time when the condition is true the 1 st row will be colored..How can I set it for i'th row?

So what is the problem here? Anything preventing you from soing that? — Guillaume Polet, Jul 19 '12 at 10:17
What's preventing you from writing `row==i`? As explained by MadProgrammer, you need to retrieve `i` somehow. From your TableModel, from a Controller, from somewhere else... — Guillaume Polet, Jul 19 '12 at 10:58
yes that I know..but I am not getting it resolved..everytime error is coming..can you suggest any way? — Luna, Jul 19 '12 at 11:01

Change boolean interestingRow = row ==1 to meet your requirements, where row == n would produce the desired result. You must define n in some meaningful way

This could come from the table data model or be supplied by other means
