You can try to add table dynamically, and add data to different Table.
Or Just add fixed number of table and add data to different table.

i am not sure what it means.
i being reading http://www.um.es/fem/EjsWiki/Main/ElementsDataTable and i don't think storing data after the previous runs is possible even if i use _initialize().


but i think i found a work around the problem.
students can open an excel spreadsheet,
select the data table one row only, and copy and paste into the excel sheet.
slowly, play each "run" and copy and paste each run's data table row into the same excel sheet, there by achieving the table for analysis and deduce the trends themselves.

This feature was suggested by student in their feedback form who went through my "research" intervention in Feb 2010
