So, I tried to export the tabular with LuaTeX instead, and the \cline problem is resolved, as mentioned in the ticket LyX does not invert the syntax with LuaTeX. The problem is that LyX use polyglossia by default with non-TeX fonts and LuaTeX, and to my knowledge there is no utility for RTL tabular with LuaLaTeX and polyglossia (i.e. all the text inside the tabular is LTR). With XeLaTeX there's the file *array*-*xetex*-*bidi*.*def, *but as the name suggest, It is only used with XeTeX and bidi. Note that most latex document classes use tabular for title (or author to be exact) and similar layouts, so this is a bit annoying ( attached a LyX file to demonstrate the problem, i tested this in master). With babel there is the option layout=tabular which fixes that, but then the tabulars need to be typed As with Xelatex and polyglossia. Would it be reasonable to format the output latex code when exporting an RTL LyX document with LuaTeX s.t it will use babel instead of polyglossia? (attached a latex file that demonstrates the format i want to achieve, it somewhat resembles this example file <https://github.com/latex3/babel/blob/main/samples/lua-hebrew.tex> from babel repository). I tried to disable all language support from lyx (no language package etc.) but then LyX behaves just as with pdflatex and RTL languages, it inserts some RTL related code by itself, e.g., \R, \L, and with babel and luatex these commands are not defined. I have one final question on the matter. Why does LyX enclose every equation with \LRE when exporting a hebrew document with XeLaTeX? I could not figured the use of that, and it somewhat clumps the exported code.
