Hello Hans,

sorry for that, here is the code I used to check some LUACODE.

\definepapersize[normal][width=14.85cm, height=21cm]

\setupbodyfont[10pt]
\enableregime[il1]
\setupcolor[xwi]

\setuplayout[backspace=16mm, 
leftmargin=15mm,leftmargindistance=1mm,topspace=10mm,header=0mm,footer=0mm,height=200mm,rightmargin=0mm,width=131mm,location=middle,marking=on]

\setuppapersize[normal][A4]
\definelayer[OngletGauche][x=0mm, y=0mm, width=\paperwidth, 
height=\paperheight]    
\setupTABLE[r][1][color=dodgerblue,align={middle,lohi},height=1cm,style={\sansserif
 \bfx},framecolor=black]

% variables
\newdimen\hauteuronglet                         %height of tab
\hauteuronglet=1cm

%variables onglet bas
\newdimen\largeurzoneongletsbas    % total width available for tabs
\newdimen\ordonneeongletsbas    % vertical position of tab
\newdimen\abscisseongletsbas    % horizontal position of tab
\newdimen\largeurongletbas              % tab width

\startluacode
        function test(opt_1, arg_1)
                local table = lpeg.split(",",interfaces.tolist(opt_1))
                local labels = lpeg.split(",",arg_1)

                print(NbTotalOnglets)

                tex.dimen.largeurongletbas = tex.dimen.largeurzoneongletsbas / 
NbTotalOnglets
                tex.dimen.abscisseongletsbas = tex.dimen.backspace + 
tex.dimen.largeurongletbas * (PremierOnglet - 1)
                
                local x_ongletsbas = tex.dimen.abscisseongletsbas - decalage
                local y_ongletsbas = tex.dimen.ordonneeongletsbas
                local largeurongletbas = tex.dimen.largeurongletbas
                                
                context.setupbackgrounds({"page"},{background = 
"OngletBas,OngletGauche,ACouper"}) 
                
                context.setlayer({"OngletBas"},{hoffset = x_ongletsbas, voffset

                context.setupTABLE({c},{1,2,3,4,5,6},{width = largeurongletbas})
                context.bTABLE()
                        context.bTR()
                                context.bTD()
                                        context(labels[1])
                                context.eTD()
                        context.eTR()
                context.eTABLE()
                )
                end
        interfaces.definecommand {
                name = "test",
                arguments = {
                { "option", "hash" },
                { "content", "string" },
                },
                macro = test,
                }
\stopluacode

\starttext
\ss
\showframe
\input{tufte}
\test[1,6,1]{GROUND EGRESS}

\stoptext

This code is not working, I get an error while calling the function, and I 
don’t understand why.

Can you explain if you have a bit of time the remark you made about the 
overload of table ?
