Summary<\/b>: June Blender explains Doug Finke’s multiplication and formatting trick. Today…the method.<\/span>\nMicrosoft Scripting Guy, Ed Wilson, is here. This is the second part of a two-part series written by June Blender, Honorary Scripting Guy. In the first part, Fun Formatting Ones—Part 1: The Task<\/a>, we discussed the task of printing Doug’s multiplication table. In this part, we’ll talk about the techniques that he used, including formatting the table.<\/p>\n

Note<\/b> If you already understand an element of the method, such as Ranges, you can skip that section. The sections are independent.\nHere’s June…\nToday, I’ll explain the techniques that Doug used to solve the task, including an interesting loop and string formatting.<\/p>\n

Recap of Part 1<\/h2>\n

Let’s recap what we learned in Part 1.\nDoug wanted to create this table of products in Windows PowerShell.<\/p>\n

       1 *        1 = 1<\/p>\n

      11 *       11 = 121<\/p>\n

     111 *      111 = 12321<\/p>\n

    1111 *     1111 = 1234321<\/p>\n

   11111 *    11111 = 123454321<\/p>\n

  111111 *   111111 = 12345654321<\/p>\n

 1111111 *  1111111 = 1234567654321<\/p>\n

11111111 * 11111111 = 123456787654321\nEach row of the table multiplies n<\/i> digits of 1s and shows the product. The number of 1-digits increases with each row. To do this, he creates a loop that goes from 1 to 8 and prints that number of 1s and their product. For each row:<\/p>\n
