Nextاین دوره آموزشی محصول موسسه است. Pivot Tables are one of the most powerful tools in Excel's data analysis armory. The data in this Excel table shows how the number of customers varies by day, and the days measure is the number of days after your company has sent out a mailer. So the first column is days, and I selected that column by moving my mouse pointer over the column header.
