Used to store content into the data table before analysis. The data that will be collected can be created from an expression, it can come from a get/post request from another page, or it can be a static value. The difference between this and the Add Column XML property is that this process occurs before any analysis is completed, versus after.
Example:
<ExtraPreData>
<Data>
<ColumnName>Event Start</ColumnName>
<ColumnType>System.String</ColumnType>
<PageRequest>StartDateNew</PageRequest>
</Data>
<Data>…</Data>
</ExtraPreData>

The type of column you want to add. Please see Convert XML/ColumnType for available options.
The static value to be stored within the property.
The expression used to store data within the column.
The Page Request variable to collect when this page is called. This can come from either a get request or a post request.
