Set Cell Color without using DefaultTableCellRenderer

Question

Hi,
Is there any possible to set the JTable cell color without using DefaultTableCellRenderer ?. For ex, I have one JTable that having 9 rows and 9 columns. I have to set the cell color in 2nd row & 3rd column.
Please anyone give me guidance to solve this.
Thanks & Regards

Fine.. Please try to understand my points.
Because in my application I have JTable that having 10 columns and rows dynamically will come based on the value fetch from arraylist. If I use DefaultTableCellRenderer, for each record its calling CustomTableCellRenderer(). For example arraylist return 10 rows means its looping 100 times(10 rows * 10 columns).
CustomTableCellRenderrer.java
ArrayList dataLiveMarket = (ArrayList) new CheckUser().getLiveMarketDetails(unval);
CustomTableModel modelLiveMarket = new CustomTableModel(dataLiveMarket);
JTable tableOne = new JTable(modelLiveMarket);
tableOne.setDefaultRenderer(Object.class, new CustomTableCellRenderer());
CustomTableCellRenderrer.java
package com.fxtrading.dao;
import java.awt.Color;
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.SwingConstants;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableModel;

public class CustomTableCellRenderer extends DefaultTableCellRenderer {
    //private TableModel bidLastPrice;
    //int k;
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
            boolean hasFocus,
            int row, int column) {
        Component component =
                super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        if (column == 0 || column == 1|| column == 2) {
            setHorizontalAlignment(SwingConstants.LEFT);
        } else if(column == 3 || column == 4 || column == 5 || column == 6 || column == 7 || column == 8){
            setHorizontalAlignment(SwingConstants.RIGHT);
        }else if(column == 9){
            setHorizontalAlignment(SwingConstants.CENTER);
        // Change cell Color - Started
        bidLastPrice = table.getModel();
        int bidLastRowCount =(int)table.getRowCount();
        for(k=0; k<bidLastRowCount; k++) {
            String bidPrice = (String)bidLastPrice.getValueAt(k,4);
            String lastPrice = (String)bidLastPrice.getValueAt(k,8);
            bidPrice = bidPrice.replace(",","").replace("$","");
            lastPrice = lastPrice.replace(",","").replace("$","");
            if(Double.parseDouble(bidPrice)<Double.parseDouble(lastPrice)){
                if(row == k && column == 4){
                    component.setBackground(Color.RED);                   
                }else{
                    component.setBackground(Color.WHITE);
                System.out.println("Row Count -->"+k+" Less ----> Bid Price----> "+Double.parseDouble(bidPrice)+" : Last Price----> "+Double.parseDouble(lastPrice));
            }else{
                if(row == k && column == 4){                  
                    component.setBackground(Color.GREEN);
                }else{
                    component.setBackground(Color.WHITE);
                System.out.println("Row Count -->"+k+" More ----> Bid Price----> "+Double.parseDouble(bidPrice)+" : Last Price----> "+Double.parseDouble(lastPrice));
        // Change cell Color - End
        return component;
