Hi,
I want to display the following data structure:
Each data element has a header and 0..n subentries within a two-column
table. My data comes from a scripted datasource.
I am wondering how to implement this. Do I need a subreport for the
subentry table mentioned above?

If your scripted data is bringing in everything you need, probably not.
Assuming you have a query returning a row like:
[header field 1][header field 2][header field n][detail field 1][detail field 2][detail field n]
You can pull that into a table in BIRT, then within the table group on one or more of your header fields. Then you can show header information in the header row, and detail information in the detail rows.

But if I get it right, the Java event handler is called once for each
row, right? So, if the handler is called once for each header, how do I
fill in the detail rows?

I think you're confusing two different loci of action.
The DataSet object uses the scripted datasource to generate a set/stream of DataSetRow elements.
The Table object then takes the set of DataSetRow elements and interprets them, in this case creating a header group and doing layout. The Table object has no connection with the DataSource; it merely consumes and processes the output of the DataSet.
One of the BIRT specialists can probably correct me if any of the above is in error.
