在JTable中添加JLabel，并改变选中的背景色
代码如下：
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); }}??
