Table Header Row Border extends past edge of table

[Bobbi]

I have created several tables with a header row that uses a 1.5-width line
style for top, sides, and verticals, and a 4.5-width shaded border for the
bottom border, and the entire row is shaded at 10%.

The problem is the 4.5 shaded border extends 1/8" beyond the right edge of
the table. It does not occur if it is a repeated header row (multiple page
table), if the border is used for any other row, and it depends on the border
(mulitple line borders will extend).

This only occurs when it prints, it is not visible on the document or print
preview. I have also printed to numerous printers so its not printer
configured.

Thanks!
