In your code you have two nested loops, the first uses i to iterate over the rows and the second uses j to iterate over the columns.

If you exchange them, you can go through the columns with i , resulting in something like:

int numFilas = tabla.length;
int numColumnas = tabla[0].length;
double array [] = new double [numColumnas];
for(int i = 0; i < numColumnas; i++) {
    SFil=0;

    for(int j = 0; j < numFilas; j++) {
        if (tabla[j][i]%2 != 0) {
               SFil++;
        }
    }
    array[i] = (100*SFil) / numColumnas;
    System.out.println("\nLa columna "+i+" tiene "+SFil+" números impares ("+array[i]+"%)");
    }
