heres the code i used t omake the numbers run in columns:

  #include<iostream>
#include<cstdlib>
#include<string.h>
using namespace std;
const int tam=6;
int M[tam][tam]; 
int main(int argc, char** argv)
{system ("Color 1E");
int fila,col; int valor=12;
for(fila=0;fila<tam;fila++)
	for(col=0;col<tam;col++)
	{
		M[fila][col]=valor;
		valor+=6;
	}
	for(fila=0;fila<tam;fila++)

	{	for(col=0;col<tam;col++)
		cout<<M[fila][col]<<"   ";
		cout<<"\n\n";

	}
 system("PAUSE");
 return 0;
}

Simply change cout<<M[fila][col]<<" "; to cout<<M[col][fila]<<" ";
