Multirow in tabularx?

Question

Can we use multirow in tabularx? It seemed not working and recognized:

\multirow{2}{*}{95\% Confidence

Full code:

\documentclass{article}
\usepackage{makecell} % for bold in table using \small
\renewcommand\theadfont{\small} % for bold in table using \small
\usepackage{tabularx, ragged2e} 
\usepackage{booktabs}

\begin{document}

\begin{table}[!ht]
\centering
    \begin{tabularx}{\textwidth}{l>{\raggedright\arraybackslash}Xccc}
    \toprule
    & &  & \thead{\small {\textbf{Statistic}}}& \thead{\small {\textbf{Std. Error}}} \\
\midrule
    \multicolumn{1}{l}{Difference} & Mean
    & & 44.20000 & 4.54068  \\
\cline{2-5}
    & \multirow{2}{*}{95\% Confidence Interval for Mean} & Lower Bound & 33.9283 & \\
\cline{3-5}
    & & Upper Bound & \54.4717 \\
\cline{2-5}
    & Kurtosis & & -1.000 & 1.334 \\
\bottomrule
    \end{tabularx}
\end{table}

\end{document}

I actually want something like below:

You can 1) if you load multirow and 2) use the = key, since you're in a fixed width column. I took the liberty to use the S column type for the last two columns, to have an alignment of the numbers on the decimal dot, and set the font for the column heads instead of hard coding each in the table. Also, I replaced the \clines with \cmidrule s to add some padding around the rules.

\documentclass{article}
\usepackage{makecell} % for bold in table using \small
\renewcommand\theadfont{\small} % for bold in table using \small
\usepackage{tabularx, ragged2e, multirow}
\usepackage{booktabs}
\usepackage{siunitx}
\renewcommand{\theadfont}{\small\bfseries}

\begin{document}

\begin{table}[!ht]
\centering
\sisetup{table-number-alignment=center}
    \begin{tabularx}{\textwidth}{l>{\raggedright\arraybackslash}XcS[table-format=-1.5]S[table-format=1.5]}
    \toprule
    & & & {\thead{Statistic}}& {\thead{Std. Error}} \\
\midrule
    \multicolumn{1}{l}{Difference} & Mean
    & & 44.20000 & 4.54068 \\
\cmidrule{2-5}
    & \multirow{2}{=}{95\% Confidence Interval for Mean} & Lower Bound & 33.9283 & \\
\cmidrule{3-5}
    & & Upper Bound & \ 54.4717 \\
\cmidrule{2-5}
    & Kurtosis & & -1.000 & 1.334 \\
\bottomrule
    \end{tabularx}
\end{table}

\end{document} 

Answer 2

I wouldn't use a \multirow directive. Instead, I would place the cell contents into a bespoke tabular environment, as is done in the following example.

\documentclass{article}
\usepackage{tabularx, % for 'tabularx' env.
            ragged2e, % for \RaggedRight macro
            booktabs, % for \toprule, \midrule, etc
            siunitx,  % for 'S' column type
            amsmath}  % for [b] option of \smash command
\sisetup{group-digits=false}
\newcolumntype{L}{>{\RaggedRight\arraybackslash}X}
\newcommand\mytab[1]{\smash[b]{%
    \begin{tabular}[t]{@{}L@{}} #1 \end{tabular}}}

\begin{document}

\begin{table}[!ht]
%%\centering % not needed
\begin{tabularx}{\textwidth}{ @{} l L l 
    S[table-format=-1.5] 
    S[table-format= 1.5] @{}}
\toprule
& & & {Statistic} & {Std.\ Error} \\
\midrule
Difference & Mean & & 44.20000 & 4.54068  \\
\cmidrule(l){2-5}
& \mytab{95\% Confidence Interval for Mean} & Lower Bound & 33.9283 & \\
\cmidrule(l){3-5}
& & Upper Bound & 54.4717 \\
\cmidrule(l){2-5}
& Kurtosis & & -1.000 & 1.334 \\
\bottomrule
\end{tabularx}
\end{table}

\end{document}

If you typeset a calstable using the package cals, spanning cells horizontally and vertically centre them, is easy.
