How to combine multirow and multicolumn in simplest example?

Question

I am facing problem to combine multicolumn and multirow together in a table. Anyone help what should be the latex code for below table?

Update

I have tried some code,

\begin{tabular}{|c|c|cc|}
    \hline
\multicolumn{2}{|c|}{}  &   \multicolumn{2}{c|}{C}  \\
    \cline{3-4}
\multicolumn{2}{|c|}{R}&   true    &   false       \\
    \hline
\multirow{2}{*}{R}      &   true    &   1   &   1   \\
\hline
            &   false   &   2       &   3           \\
    \hline
\end{tabular}

Output:

It's splitting the row. And I don't know how to make column margin at the top.

\multirow and multicolumn cells ... show what you try so far that we can simly show, how to use them. See https://tex.stackexchange.com/questions/375581/multirow-multicolumn-combination-problem?rq=1 (your question can be duplicate to this). — Zarko, Nov 17 '19 at 18:42
@Zarko this is not same question. I am facing problem, when I add \hline it crosses the row margin and splits the row. — Sazzad Hissain Khan, Nov 17 '19 at 18:45
One \hline (use \cline instead of tit) should not be a problem. Show us, what you try so far. Otherwise your question is "do-this-instead-of-me" and will be closed us to broad or as duplicate (what for sure it is) — Zarko, Nov 17 '19 at 18:49

Probably one of the following suggestion helps:

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

\begin{tabular}{|c|c|c|}
\hline
\multirow{2}{*}{R} & \multicolumn{2}{c|}{C} \\ \cline{2-3}
                   & C1 & C2               \\ \hline
r1                 & a  & b                \\ \hline
r2                 & a  & b                \\ \hline
\end{tabular}



\begin{tabular}{|c|c|c|c|}
    \hline
\multicolumn{2}{|c|}{\multirow{2}{*}{R}}  &   \multicolumn{2}{c|}{C}  \\
    \cline{3-4}
\multicolumn{2}{|c|}{}                    &   true    &   false       \\
    \hline
\multirow{2}{*}{R}      &   true          &   1       &   1           \\
\cline{2-4}
                        &   false         &   2       &   3           \\
    \hline
\end{tabular}
\end{document}

adding a table from your mwe.

   \documentclass{article}
   \usepackage{multicol, multirow}

   \begin{document}
   \begin{table}
   \centering
   \caption{captionless table}
   \label{tab:example}
   \renewcommand\multirowsetup{\centering}
   \begin{tabular}{|c|c|c|}
   \hline
   & \multicolumn{2}{c|}{C}\\
   \cline{2-3}
   \multirow{-2}{*}{R} & c1 & c2\\
   \hline
   r1 & a & b\\
   \hline
   r2 & c & d\\
   \hline
   \end{tabular}

   \end{table}

\begin{tabular}{|cc|c|c|}
   \hline
\multicolumn{2}{|c}{\multirow{2}{*}{R}}  &  \multicolumn{2}{|c|}{C}  \\
   \cline{3-4}
 &   true    &   false       \\
   \hline
\multicolumn{1}{|c|}{\multirow{2}{*}{R}}   &   true    &   1   &   1   \\
\cline{2-4}
\multicolumn{1}{|c|}{}          &   false   &   2       &   3           \\
   \hline
\end{tabular}

 \end{document}

For this MWE you not need multicol package! – Zarko Nov 17 '19 at 18:57
You might want to replace \cline{3-4} & true & false \\ with \cline{3-4} & & true & false \\. Otherwise, the cells are shifted to the left. – leandriis Nov 17 '19 at 19:29

In {NiceTabular} of nicematrix, you have a built-in command \Block to merge cells both horizontally and vertically. The key hvlines draws all the rules excepted in the blocks.

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{cccc}[hvlines]
\Block{2-2}{R} &       & \Block{1-2}{C} \
               &       & true & false \
\Block{2-1}{R} & true  & 1    & 1 \
               & false & 2    & 3 
\end{NiceTabular}
\end{document}
