Unwanted newline after a tcolorbox

Question

How to avoid new line jump after each tcolorbox ?

\documentclass[10pt,a5paper,landscape]{article}
\usepackage{pgffor,luacode,array,tcolorbox,bm,geometry}

\geometry{margin=1.5cm}
\pagestyle{empty}

\begin{luacode}
function Table (n)
    for i=1,10
    do
        tex.print(i.."&\\bm{"..n.."}&"..i*n.."\\\\")
    end
end
\end{luacode}

\newcommand{\Table}[1]{%
    \begin{tcolorbox}[width=.18\linewidth,colback={white},
        title={\textbf{\vphantom{Éq}%
        \Large\hfill\textsf{Table de #1}\hfill\strut}},%
        colbacktitle=gray!75,coltitle=white,
        left=1mm,top=1mm,right=1mm,bottom=1mm]
    \large
    \hfill$\begin{array}{r@{\;$\times$\;}c@{\;=\;}r}
        \directlua{Table(#1)}
    \end{array}$\hfill\strut
    \end{tcolorbox} bob}

\begin{document}

\foreach \i in {1,...,5} {\Table{\i}}

\end{document}

Answer 1

Normally tcolorbox try to typeset the box as a paragraph; to do that sets the keys before and after to a value that is dependent on the presence or not of the package parskip (guessed, really). Typically they are something like:

before={\par\pagebreak[0]\smallskip\parindent=0pt}, after={\par\smallskip}

If you want to clear the default values, use the key nobeforeafter; in the manual (pag. 78 in my copy, version 4.12) it states:

Abbreviation for clearing the keys before and after. The colored box is not put into a paragraph and there is no space before or after the box.

Moreover, the option hbox is needed sometime; this will size the box according to the content (and no the other way around; pag. 94):

capture=hbox: This is the default mode for \tcbox. The content cannot have a lower part and cannot be broken. The colored box is sized according to the dimensions of the content. A shortcut to set this mode is /tcb/hbox.
