Read the colortbl manual: The \rowcolor command has two optional
arguments to deal with such issues:
\rowcolor[⟨color model⟩]{⟨color⟩} [⟨left overhang⟩][⟨right overhang⟩]

Your example file works here as expected - four empty cells with borders in LyX, four coloured empty cells with all borders after compilation with pdflatex oder lualatex in the resulting PDF. This is with LyX 2.4.4 and $ lualatex -v This is LuaHBTeX, Version 1.22.0 (TeX Live 2025) Tobias -- lyx-users mailing list [email protected] https://lists.lyx.org/mailman/listinfo/lyx-users
