Microsoft Table

I have two questions on Word table:

1. Is there a way to put the second duplicate row as blank?  Can I use Word existing functions to set this up?  If not, would this be a VBA macros question.  The Word document is a template and will populate data when generating a report.

2.  How to set columns in a table length fixed?  So when data is populated the columns will not shrink or expand the width?

Thanks
