I found several problems in the displayTable function. I'm not sure what the lowest value for offset is supposed to be, but I went with 0 = no shift = 1st on Sunday.
The extra spaces following the \n line 38, the +1 line 49, the offset = -1 line 36 all contributed to the problem.
Here's a version which is working for all offset values of 0-6.
The lines commented out are what you had, so you can see what I changed.

   int dow = 1;// what's this for?

   cout << "  Su  Mo  Tu  We  Th  Fr  Sa\n";
//   for (int count = 1; count < offset; count++)
   for (int count = 0; count < offset; count++)
   cout << "    ";
   dow++;// not used anywhere

   for (int days = 1; days < numDays; days++)
   {
      cout << "  ";
   if (days < 10) //days are set to only have one space not 2
      cout << " ";
      cout << days;

   if ((offset + days) % 7 == 0)
      cout << "\n";

   }
   return;
