Can't export formatted search results to Excel

Hi

Trying to generate an Excel sheet from a table using the ExcelImportExportPlugin plugin.

This works fine for a static table but if I generate the table of data from a formated search the resulting spreadsheet is blank, save for the header. Originally I defined the header within the search, in which case the spreadsheet is completely blank.

Here's a test Topic I'm using:

%TABLE2EXCEL{}%

|*Topic name*|
%SEARCH{ 
   ".*testing.*"
   type="regex" 
   nonoise="on" 
   nosearch="on" 
   format="| [[$topic]] | "
}%

Thanks in advance for any help.
