Java Programming

I have the following code:

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

import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;

class ColoredTableCellRenderer
    extends DefaultTableCellRenderer
{
    public Component getTableCellRendererComponent
        (JTable table, Object value, boolean selected, boolean focused, int row, int column)
    {
        setEnabled(table == null || table.isEnabled()); // see question above

        if ((row % 2) == 0)
            setBackground(Color.green);
        else
            setBackground(Color.lightGray);

        super.getTableCellRendererComponent(table, value, selected, focused, row, column);

        return this;
    }
}

And

		//JTable
		String[] head = {"Namn", "M�ndag", "Tisdag", "Onsdag", "Torsdag", "Fredag"};
		String[][] data = {{"Niklas", "9-15", "9-15", "9-15", "9-15","9-15"}, 
							{"Niklas", "9-15", "9-15", "9-15", "9-15","9-15"}}; 
		JTable table = new JTable(data, head);
		JScrollPane centerFrame = new JScrollPane(table);
		//table.setEnabled(false);
		table.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
		
		TableColumnModel tcm = table.getColumnModel();
		TableColumn tm = tcm.getColumn(0);
		tm.setCellRenderer(new ColoredTableCellRenderer());

I want the possibility to change background color to one row, column or cell, but as i have read on the net and taken code from the above code should change the color per row. And thats correct, but it changes the code only for the one column!
I want to change the entire row or column!

Plz help!
