CustomJTable.java

import java.awt.Color;
import java.awt.Component;

import javax.swing.JComponent;
import javax.swing.JTable;
import javax.swing.table.TableCellRenderer;

public class CustomJTable extends JTable {

 	Color backgroundColor = getBackground();
	Color foregroundColor = getForeground();
	
	@Override
    	public Component prepareRenderer(TableCellRenderer renderer, int rowIndex,
            int columnIndex) {
        JComponent component = (JComponent) super.prepareRenderer(renderer, rowIndex, columnIndex);  

        if(columnIndex == 4){
            if(getValueAt(rowIndex, 4).toString().equalsIgnoreCase("0")) {
                component.setBackground(Color.GREEN.darker());
                component.setForeground(Color.GREEN.darker());
            }else  {
                component.setBackground(Color.GRAY.brighter());
                component.setForeground(Color.GRAY.brighter());
            } 
        }else{
        	component.setBackground(backgroundColor);
            component.setForeground(foregroundColor);
        }      
        
        return component;
    }
}

This code changes the Fifth column background co lour to Green if the Cell value is 0, otherwise it will be gray.
