java swing控件JTable 怎么单独设置某一行的颜色

下面是一个例子的代码：（getTableCellRendererComponent）

colorTableRender colorRender = new colorTableRender ();
table.getColumn("A").setCellRenderer(colorRender);//A,B,C分别代表列名
table.getColumn("B").setCellRenderer(colorRender);
table.getColumn("C").setCellRenderer(colorRender);

public class colorTableRender extends DefaultTableCellRenderer {

public Component getTableCellRendererComponent(JTable table,
Object value, boolean isSelected, boolean hasFocus, int row,
int column) {
Component cell = super.getTableCellRendererComponent(table, value,
isSelected, hasFocus, row, column);
if (row <6) //这里设置行数
cell.setBackground(Color.WHITE);
else
cell.setBackground(new Color(0xee,0xee,0xee));
return cell;

}
}
