JTable에 JLabel을 추가하고 선택한 배경색을 변경합니다

코드는 다음과 같습니다.

import javax.swing.JLabel;
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;

public class Renderer extends DefaultTableCellRenderer{

    public void fillColor(JTable t,JLabel l,boolean isSelected ){
        //setting the background and foreground when JLabel is selected
        if(isSelected){
            l.setBackground(t.getSelectionBackground());
            l.setForeground(t.getSelectionForeground());
        }

        else{
            l.setBackground(t.getBackground());
            l.setForeground(t.getForeground());
        }

    }

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
         boolean hasFocus, int row, int column)
     {

        if(value instanceof JLabel){
            JLabel label = (JLabel)value;
            //to make label foreground n background visible you need to
            // setOpaque -> true
            label.setOpaque(true);
            fillColor(table,label,isSelected);
            return label;

        }

        else
            return super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
     }

}
