Two nested loops can be used to output the multiplication table of 9×9: the outer loop controls the number of rows in the table, while the inner loop controls the number of columns in each row.

Here is an example code for implementing the multiplication table of nine using Scala.

object MultiplicationTable {
  def main(args: Array[String]): Unit = {
    for (i <- 1 to 9) {
      for (j <- 1 to i) {
        print(j + " * " + i + " = " + (i * j) + "\t")
      }
      println()
    }
  }
}

By running the above code, you can generate the following multiplication table for the nine times table.

1 * 1 = 1
1 * 2 = 2	2 * 2 = 4
1 * 3 = 3	2 * 3 = 6	3 * 3 = 9
1 * 4 = 4	2 * 4 = 8	3 * 4 = 12	4 * 4 = 16
1 * 5 = 5	2 * 5 = 10	3 * 5 = 15	4 * 5 = 20	5 * 5 = 25
1 * 6 = 6	2 * 6 = 12	3 * 6 = 18	4 * 6 = 24	5 * 6 = 30	6 * 6 = 36
1 * 7 = 7	2 * 7 = 14	3 * 7 = 21	4 * 7 = 28	5 * 7 = 35	6 * 7 = 42	7 * 7 = 49
1 * 8 = 8	2 * 8 = 16	3 * 8 = 24	4 * 8 = 32	5 * 8 = 40	6 * 8 = 48	7 * 8 = 56	8 * 8 = 64
1 * 9 = 9	2 * 9 = 18	3 * 9 = 27	4 * 9 = 36	5 * 9 = 45	6 * 9 = 54	7 * 9 = 63	8 * 9 = 72	9 * 9 = 81
