Problem using multirow in two places

Question

I'm trying to get two multirows separated by several columns, but it wants to add an extra row in the table. My code is:

\documentclass[]{article}
\usepackage{multirow,booktabs}
\begin{document}
\begin{table}[!htbp]
    \begin{center}
     \caption{Stuff.}
      \begin{tabular}{cc|ccc|cc|ccc}
         \toprule
         \multicolumn{5}{c|}{Single Smoothing (SS)}&\multicolumn{5}{c}{Double Smoothing (DS)}\\
         \midrule
Measure &   Method &    $h=1$   &   $h=6$   &   $h=12$  &   Measure &   Method  &   $h=1$   &   $h=6$   &   $h=12$  \\
\midrule
\multirow{4}{*}{sME}    &&&&&   \multirow{4}{*}{sME}    \\
    &   SS  &   -0.312  &   -8.605  &   -3.342  &       &   DS  &   -0.315  &   -0.175  &   -0.238  \\
  & Mean    &   -0.664  &   0.462   &   -0.543  &     & Mean    &   -0.484  &   -0.290  &   -0.308  \\
    &   Naive   &   0.064   &   -0.433  &   -0.589  &       &   Naive   &   -1.364  &   -0.786  &   0.108   \\
    &   Autobox &   -0.578  &   -1.947  &   -0.702  &       &   Autobox &   -1.784  &   -0.201  &   -0.294\\
\bottomrule
\end{tabular}
\end{center}
\end{table}
\end{document}

The out put looks like this, but I don't want the extra row.

You get the extra row because you didn't put any content in the row with the \multirows. Try this:

\documentclass[]{article}
\usepackage{multirow,booktabs}
\begin{document}
\begin{table}[!htbp]
    \begin{center}
     \caption{Stuff.}
      \begin{tabular}{cc|ccc|cc|ccc}
         \toprule
         \multicolumn{5}{c|}{Single Smoothing (SS)}&\multicolumn{5}{c}{Double Smoothing (DS)}\\
         \midrule
         Measure &   Method &    $h=1$   &   $h=6$   &   $h=12$  &   Measure &   Method  &   $h=1$   &   $h=6$   &   $h=12$  \\
         \midrule
         \multirow{4}{*}{sME} & SS & -0.312  & -8.605 & -3.342 & \multirow{4}{*}{sME} &   DS  &   -0.315  &   -0.175  &   -0.238  \\
             % &   SS  &   -0.312  &   -8.605  &   -3.342  &       &   DS  &   -0.315  &   -0.175  &   -0.238  \\
           & Mean    &   -0.664  &   0.462   &   -0.543  &     & Mean    &   -0.484  &   -0.290  &   -0.308  \\
             &   Naive   &   0.064   &   -0.433  &   -0.589  &       &   Naive   &   -1.364  &   -0.786  &   0.108   \\
             &   Autobox &   -0.578  &   -1.947  &   -0.702  &       &   Autobox &   -1.784  &   -0.201  &   -0.294\\
\bottomrule
\end{tabular}
\end{center}
\end{table}
\end{document}

P.S.: Are you sure you want those vertical lines? The booktabs package emphasizes that you shouldn't. Here's an alternative without them:

\documentclass[]{article}
\usepackage{multirow,booktabs}
\begin{document}
\begin{table}[!htbp]
    \begin{center}
     \caption{Stuff.}
      \begin{tabular}{cccccccccc}
         \toprule
         \multicolumn{5}{c}{Single Smoothing (SS)}&\multicolumn{5}{c}{Double Smoothing (DS)}\\
         \cmidrule(lr){1-5} \cmidrule(lr){6-10}
         Measure &   Method &    $h=1$   &   $h=6$   &   $h=12$  &   Measure &   Method  &   $h=1$   &   $h=6$   &   $h=12$  \\
         \cmidrule(lr){1-5} \cmidrule(lr){6-10}
         \multirow{4}{*}{sME} & SS & -0.312  & -8.605 & -3.342 & \multirow{4}{*}{sME} &   DS  &   -0.315  &   -0.175  &   -0.238  \\
             % &   SS  &   -0.312  &   -8.605  &   -3.342  &       &   DS  &   -0.315  &   -0.175  &   -0.238  \\
           & Mean    &   -0.664  &   0.462   &   -0.543  &     & Mean    &   -0.484  &   -0.290  &   -0.308  \\
             &   Naive   &   0.064   &   -0.433  &   -0.589  &       &   Naive   &   -1.364  &   -0.786  &   0.108   \\
             &   Autobox &   -0.578  &   -1.947  &   -0.702  &       &   Autobox &   -1.784  &   -0.201  &   -0.294\\
\bottomrule
\end{tabular}
\end{center}
\end{table}
\end{document}

You can say \cmidrule(l){i-j} or \cmidrule(r){i-j} or \cmidrule(lr){i-j} to shorten the \cmidrule on the left, on the right, or on both sides respectively.

I propose these layout improvements: splitting the table in two subtables, and using siunitx for a better formatting of the numbers in columns 3 to 5:

\documentclass[]{article}
\usepackage[showframe]{geometry}
\usepackage{multirow,booktabs, subcaption}
\usepackage{siunitx}

\begin{document}
\begin{table}[!htbp]
\centering\setlength{\tabcolsep}{4pt}
\sisetup{table-format=-1.3, table-number-alignment=center}
     \caption{Stuff.}
\noindent\begin{subtable}{0.48\linewidth}\centering
\caption{Single Smoothing (SS)}
      \begin{tabular}{cc*{3}{S}}
         \toprule
         Measure & Method & {$h=1$} & {$h=6$} & {$h=12$} \\
         \midrule
         \multirow{4}{*}{sME} & SS & -0.312 & -8.605 & -3.342 \\
           & Mean & -0.664 & 0.462 & -0.543 \\
             & Naive & 0.064 & -0.433 & -0.589 \\
             & Autobox & -0.578 & -1.947 & -0.702 \\
\bottomrule
\end{tabular}
\end{subtable}
\hfill
\begin{subtable}{0.48\linewidth}\centering
\caption{Double Smoothing (DS)}
 \begin{tabular}{cc*{3}{S}}
 \toprule
 Measure & Method & {$h=1$} & {$h=6$} & {$h=12$} \\
 \midrule
 \multirow{4}{*}{sME} & DS & -0.315 & -0.175 & -0.238 \\
  & Mean & -0.484 & -0.290 & -0.308 \\
   & Naive & -1.364 & -0.786 & 0.108 \\
   & Autobox & -1.784 & -0.201 & -0.294\\
\bottomrule
\end{tabular}
\end{subtable}
\end{table}

\end{document}
