Need help with spacing

[keltonfan2]

I have a program that prints out pascal's triangle. One problem: it isn't a triangle. The output doesn't work. This is what it should print:

How many rows: 4
                 1
              1     1
           1     2     1
        1     3     3     1
     1     4     6     4     1

and this is what it does print:

Enter a number of rows: 4
            1
            1           1
            1           2            1
            1           3            3            1
            1           4            6            4            1

Can someone help me get the spacing right? My code is:

#include <iostream>
#include <iomanip>
using namespace std;
int combinations (int n, int k) {
    if (k == 0 || k == n) {
        return 1;
    }
    else {
        return combinations(n-1,k-1) + combinations(n-1,k);
    }
}
int main ( ) {
    int rows;
    cout << "Enter a number of rows: ";
    cin >> rows;
    for(int r = 0; r < rows+1; r++) {
            cout << "            " << "1";
        for(int c = 1; c < r+1; c++) {
                     
            cout << "           " << combinations(r, c) << ' ';
            
        }
        cout << endl;
    }
}

1st cout:

cout<<"  ";

2nd cout:

cout<<"    "<<coef;

3rd cout:

cout<<endl;

If you need further help, let me know.
