Expected output: two tables at the same row such that the common wall/edge is bold as clear separator

Another example as 1x3 with 4 tables

Show 1x3 table structure i.e. one table at the left-hand-side and there tables at the right-hand-side such that many common edges. Code and its output in Fig. 2

Silly question: Why do you want to do it as two tables and not as one? — Aradnix, Aug 08 '17 at 17:36
We've had this before. The two tables are adjacent because you have a line-break between the two tabulars. — Werner, Aug 08 '17 at 17:40
Please, be realistic, the last example has four tables with a width of .5\linewidth. How should they fit in a line? — Heiko Oberdiek, Aug 08 '17 at 18:25
@HeikoOberdiek One table at the left-hand-side, while three tables at the right-hand-side at one column. — Léo Léopold Hertz 준영, Aug 08 '17 at 18:26

A variant for two tables side by side:

Environment tabularx of package tabularx for the X column to maximize the place for the column with the summary.
Nicer lines with package booktabs
Units with package siunitx
...

Example file:

\usepackage{booktabs}

\newcommand*{\MakeCell}[1]{%
  \begingroup
    \renewcommand*{\arraystretch}{1}% reset if changed
    \begin{tabular}[b]{@{}c@{}}%
    #1%
    \end{tabular}%
  \endgroup
}

\begin{document}

    \noindent
    \begin{tabularx}{.49\linewidth}[t]{ l l l X }
    \toprule
    Day & \MakeCell{Min.\\temp.} & \MakeCell{Max.\\temp.} & Summary \\
    \midrule
    Monday & \SI{11}{\celsius} & \SI{22}{\celsius}
    & A clear day with lots of sunshine.
      However, the strong breeze will bring down the temperatures. \\
    \addlinespace
    Tuesday & \SI{9}{\celsius} & \SI{19}{\celsius}
    & Cloudy with rain, across many northern
      regions. Clear spells
      across most of Scotland and Northern Ireland,
      but rain reaching the far northwest. \\
    \addlinespace
    Wednesday & \SI{10}{\celsius} & \SI{21}{\celsius}
    & Rain will still linger for the morning.
      Conditions will improve by early afternoon and continue

With a vertical rule instead of padding to separate the tables:

\end{tabularx}%
\kern-.2pt %
\vrule % default width is 0.4 pt
\kern-.2pt %
\begin{tabularx}{.5\linewidth}[t]{ l l l X }

Variant with one large table on the left and three small tables at the right:

\documentclass{article}
\usepackage{xcolor}
\begin{document}

\newcommand*{\TableA}{%
  \textcolor{gray}{\rule{.5\linewidth}{10cm}}%
}
\newcommand*{\TableB}{%
  \textcolor{red}{\rule{.5\linewidth}{3cm}}%
}
\newcommand*{\TableC}{%
  \textcolor{green}{\rule{.5\linewidth}{3cm}}%
}
\newcommand*{\TableD}{%
  \textcolor{blue}{\rule{.5\linewidth}{3cm}}%
}
\sbox0{\TableA}%
\noindent
\vtop{%
  \kern0pt % Align at the top
  \copy0 %
}%
\kern-.2pt %
\vrule
\kern-.2pt %
\vtop to \dimexpr\ht0+\dp0{%
  \kern0pt % Align at the top
  \hbox{\TableB}%
  \vfill
  \hbox{\TableC}%
  \vfill
  \hbox{\TableD}%
}
\end{document}

Other variant:

\documentclass{article}
\usepackage{xcolor}
\begin{document}

\newcommand*{\TableA}{%
  \textcolor{gray}{\rule{.5\linewidth}{10cm}}%
}
\newcommand*{\TableB}{%
  \textcolor{red}{\rule{.5\linewidth}{3cm}}%
}
\newcommand*{\TableC}{%
  \textcolor{green}{\rule{.5\linewidth}{3cm}}%
}
\newcommand*{\TableD}{%
  \textcolor{blue}{\rule{.5\linewidth}{3cm}}%
}
\noindent
\vtop{%
  \kern0pt % Align at the top
  \hbox{\TableA}%

\kern-.2pt %
\vrule
\kern-.2pt %
\vtop{%
