previous row value in data table in Spotfire

This is super easy in excel.. Couldn't find it this in Spotfire easily.. Quick help would be appreciated.

Question:

In the calculated column, I like to add previous row data. For example, in attached sheet calculated column "Previous CODE". I like add data of Column "CODE" from previous row.

Please let me know incase something is unclear.

您可以使用具有以下表达式的计算列来实现此目的:

First([CODE]) OVER Previous([EVENT_DATE])
