Well, the introduction of table borders causes LyX to introduce 
"multicolumns" of one column each, which somehow seems to conflict 
(slightly) with the \rowcolor command. Maybe a TeXpert can figure out a 
workaround, but I suspect this is one of those LaTeX things you just 
need to accept ... unless maybe you want to experiment with using LaTeX 
commands to introduce the border lines yourself.

FWIW, I tried editing the LaTeX to move the \rowcolor file before rather 
than in the first cell. It seemed to fix the problem, but I can't find 
any way in LyX to wedge a custom command/setting into a table before the 
first row. The Embedded Objects help manual says to color rows the way 
you are currently doing it, if that is any consolation.
