The bug: reLyX does not translate "\ " and "~" (protected spaces) inside tabulars correctly.
reLyX has subsequently been modified to translate '~' to protected_separator. My LaTeX knowledge is insufficient to say that there is no LaTeX difference at all between '~' and '\ '. Can someone knowledgable advise? If there is no difference, then I guess it's reasonable to translate '\ ' to protected_separator also. I have done a test with this latex file: \documentclass{article} \begin{document} \begin{tabular}{|c|c|} \hline a~a~a~a& b~b~b~b \\ \hline \end{tabular} \end{document} If I replace all the '~' above with '\ ', the two dvi files are identical. Nonetheless, I'd like confirmation that this is the right thing to do. -- Angus
