How can I select data grid row in form task?

So in my workflow, I get data from a database, then I display the data in a form task (using create form task activity). I need to make it possible for the person that the form task will be assigned to, to select one row.

We used to do this in a drop down - we merged all the columns of the database in a string and put them in a dropdown in the form task, but we decided to go with a table instead. Is there a way to do this using a table?

@sangL - would you be able to help?
