Try this:{its in java but adjust it accordingly}
// it does work

public class Test {
   public  void Multiply(int a, int b){
            int i;
            System.out.println("\t");
            for (i = a; i <= b; i++){
                System.out.print(" "+" "+"\t"+i);}
                System.out.print("  "+" "+"\n");

            for (i = a; i <= b; i++){
                System.out.print(i + "\t");
                for (int j = a; j <= b; j++){
                    System.out.print(i * j+" " + "\t" +"");
                }
                System.out.print("\n");
            }
        }
    }

public class testTest {
 public static void main(String[] args){
