18.10.1.22 dataField (Data Field Item)
Represents a field from a source list, table, or database that contains data that is summarized in a PivotTable.

A data field represents data that is derived from a field in the source list or database. [Example: The Sport field, for example, might come from a column in the source list that is labeled Sport and contains the names of various sports (Golf, Tennis) for which the source list has sales figures. end example]
Source data can be taken from an SpreadsheetML list or range, an external database or cube, or another PivotTable. Data fields use summary functions to combine values from the underlying source data. You can also use custom calculations to compare data values, or add your own formulas that use elements of the report or other worksheet data.
[Example:
<dataFields count="1">
<dataField name="Sum of Sales Amount" fld="25" baseField="0" baseItem="0"/>
</dataFields>
end example]
