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
 

C++

#include <iostream>
 
using namespace std;
 
void main()
{
 
	int row = 1;
 
	while ( row <= 9)
	{
		for (int col = 1; col <= row; col++)
		{
	//	cout << row << "\t";
		cout << col << "*" << row << "=" << col*row << "\t";
		}
		row++;
		cout << endl;
	}
}

Python

row = 1
col = 1
 
while row <= 9:
    # print(" *" * row)
    col = 1
    while col <= row:
        print(" %d * %d = %d " % (col, row, col*row), end=" ")
        col += 1
    print("\n")
    row += 1
