Sounds like a bug, but probably in something other than colortbl. Can you produce a minimal but complete demonstration file?

It is a bug in colortbl. I had expected some accents were defined to use raw \halign without empying \everycr, but colortbl subverts \everycr to prevent it being emptied properly.

The comments in colortbl.dtx give no indication why \everycr has to be subverted instead of just set. Give it a try with this patch

\usepackage{colortbl}
\makeatletter
\let\everycr\CT@everycr % restore proper
\g@addto@macro\CT@start{\CT@hookeverycr}
\def\CT@hookeverycr{%
  \everycr{\noalign{\global\let\CT@row@color\relax}}%
  \def\everycr##1{\let\everycr\CT@everycr}}
\makeatother

The suggestion by Donals Arseneau works fine for multicolum tables. Thanks for all the help.
