SSRS 2008 - Hidden row and column at end of tablix when exporting to excel

Hi,

I am using SSRS 2008 and have a report with a single tablix.

After exporting to excel, at the end of the tablix (and data) there is a single row with a height of zero and there is a column with a height of width of zero at the right of the tablix. 

Does anyone know what I can do to fix this?

The following thread has some suggestions but none of them worked:
