How to print the arrays in table or dimension format?

Question

Actually this works

 object Matrixmul extends App {
 val a = Array(Array(1, 2, 3), Array(4, 5, 6), Array(7, 8, 9))
 val b = Array(Array(1, 2, 3), Array(4, 5, 6), Array(7, 8, 9))
 val c = Array.ofDim[Int](3, 3)
 val sum =Array.ofDim[Int](3,3)
 println(a.mkString(" "))
 val elements = for {
  row <- a
  ele <- row
   }yield ele
   for(array1 <-elements)
 println(" the 1st matrix array elements are : " + array1)

This prints the arrray in the format,

the 1st matrix array elements are : 1
the 1st matrix array elements are : 2
the 1st matrix array elements are : 3
the 1st matrix array elements are : 4
the 1st matrix array elements are : 5
the 1st matrix array elements are : 6
the 1st matrix array elements are : 7
the 1st matrix array elements are : 8
the 1st matrix array elements are : 9

But I need in DIMENSION format,

1 2 3
4 5 6
7 8 9

[1 2 3] [4 5 6] [7 8 9] in matrix format

How about the following,

val a = Array(Array(1, 2, 3), Array(4, 5, 6), Array(7, 8, 9))

a.foreach(row => println(row.mkString(" ")))

Which will print your dimentional format,

1 2 3
4 5 6
7 8 9

YES , It works. Thanks for the solution. EVEN this also works println(" The 1 st ARRAY MATRIX ARE : " + "\n"+ a.deep.mkString(" \t \n"))

Small variation on the subject

val a = Array(Array(1, 2, 3), Array(4, 5, 6), Array(7, 8, 9))

println(a.map(_.mkString(" ")).mkString("\n"))
