If you have given A1:A5 the name Addends, you can use this instead of SUM(A1:A5): You might already know that you can assign a name to a worksheet range and use that name instead of a range address. The way I prefer to handle that is by means of dynamic range names. If you now put a new value in A6, SUM() doesn’t change itself from SUM(A1:A5) to SUM(A1:A6). You have to do something special to refresh the table when the underlying data changes.īut even SUM() won’t change its own argument. That’s not true of a pivot table that’s based on those cells or any other cell. In some cell, the value it returns changes immediately if you change any of the values in A1:A5. ![]() ![]() In contrast, something as simple as the SUM() function can update itself when the underlying values change. When you connect this pivot table to a pivot chart, you can start making real sense of the data.Īs powerful as pivot tables are-and I believe that pivot tables are the most powerful and flexible tool for data synthesis and analysis available in Excel-they can’t tell when you have changed the underlying data, and (without help) they can’t tell that their underlying data range has added another row.
