Repeating table rows in template?

[TheWedgie]

Using Word 2007, is it possible to have repeating rows in a table as part of a template.
For example, in the document below, I'd like people to be able to enter any number of crewing details, but only have the document show the table rows where there's data - whether this is by hiding empty rows, or by enabling them to add more rows.
What I'd like to restrict though, is any editing of the table itself.
