Dear Hans,

Thank you for your suggestions.

I changed the code without the intermediate variables.

I works well.

good, so now we're ready for a next improvement:

    local tf = { true, false }

    function document.truthTable(a)
        document.MakeHead(a)
        for i,s in ipairs(tf) do
            for j,t in ipairs(tf) do
                for k,u in ipairs(tf) do
                    context.NC()
                    context(s and "1" or "0")
                    context.NC()
                    context(t and "1" or "0")
                    context.NC()
                    if #a == 3 then
                        break
                    end
                    context(u and "1" or "0")
                    context.NC()
                    context(document.logicFa(s,t,u))
                    context.NC()
                    context.AR()
                end
                if #a == 3 then
                    context(document.logicF2(s,t))
                    context.NC()
                    context.AR()
                end
            end
        end
        document.MakeFooter()
    end

and after that

    local tf = { "1", "0" }

    function document.truthTable(a)
        document.MakeHead(a)
        for i,s in ipairs(tf) do
            for j,t in ipairs(tf) do
                for k,u in ipairs(tf) do
                    context.NC()
                    context(s)
                    context.NC()
                    context(t)
                    context.NC()
                    if #a == 3 then
                        break
                    end
                    context(u)
                    context.NC()
                    context(document.logicFa(s,t,u))
                    context.NC()
                    context.AR()
                end
                if #a == 3 then
                    context(document.logicF2(s,t))
                    context.NC()
                    context.AR()
                end
            end
        end
        document.MakeFooter()
    end
