Changing a cell's background color in a JTable
How to change the color of the individual cells based on the value that they contain?
Here's what I have based on what I've found.

@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
int row, int column) {
// TODO Auto-generated method stub
return null;
}
}
Then heres the renderer class that should change the background color
import java.awt.Color;
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;
public class MyRenderer extends DefaultTableCellRenderer
{
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
{
Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
if (((int)table.getValueAt(row, column)) == 1)
{
System.out.println("hi");
}
else
{
c.setBackground(table.getBackground());
}
return c;
}
}

your code has lots of bad smell, if you don't know how to make it better, I recommend you to read some books like Refactoring: Improving the design of existing code and Effective Java.
Anyway, I made it work, please check whether it's what you want.

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
DriversSeason1 window = new DriversSeason1();
window.frameSeason1Drivers.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
MyRenderer myRenderer = new MyRenderer();
tableSeason1Drivers.setDefaultRenderer(Object.class, myRenderer);
}
The main method runs on a separate Thread so you are attempting to add the renderer to the table BEFORE the DriversSeason1 class is created.
Then when the code on the Event Dispatch Thread executes your DriverSeason1 class is created and you create a new JTable so all the custom renderers are lost.
The solution is simple. Add the renderer to the table when you create the table.
Also, you DriversSeason1 class should NOT extend JLabel and implement TableCellRenderer. Get rid of all that code.
Finally, when you fix these problems you will still have an error in the renderer which should be obvious. You load the data as String objects so you can't expect to create the object and an Integer. You need to do a String comparison in your code, not an integer comparison.
