[Tex/LaTex] “! Undefined control sequence.” errors with table

Question

I want to insert a table into my document with latex:

\begin{table}[htbp]
  \centering
  \caption{}
    \begin{tabular}{l|l|l|l|l|l|l}
    \hline
    \hline
    \multicolumn{1}{r}{\multirow{}} & \multicolumn{2}{c|}{\textbf{S\&P500}} & \multicolumn{2}{c|}{\textbf{GS10}} & \multicolumn{2}{c}{\textbf{TWEXMMTH}} \bigstrut\\
\cline{2-7}    \multicolumn{1}{r}{} & \multicolumn{1}{c|}{\textbf{p-value}} & \multicolumn{1}{c|}{\textbf{Yes/No}} & \multicolumn{1}{c|}{\textbf{p-value}} & \multicolumn{1}{c|}{\textbf{Yes/No}} & \multicolumn{1}{c|}{\textbf{p-value}} & \multicolumn{1}{c}{\textbf{Yes/No}} \bigstrut\\
    \hline
    \hline
    \textbf{PFANDB} & 0,000 & Yes   & 0,193 & No    & 0,487 & No \bigstrut\\
    \hline
    \textbf{PRAWM} & 0,001 & Yes   & 0,287 & No    & 0,601 & No \bigstrut\\
    \hline
    \textbf{PNRG} & 0,001 & Yes   & 0,002 & Yes   & 0,543 & No \bigstrut\\
    \hline
    \textbf{PMETA} & 0,014 & Yes   & 0,052 & No    & 0,537 & No \bigstrut\\
    \hline
    \textbf{GOLD} & 0,359 & No    & 0,709 & No    & 0,166 & No \bigstrut\\
    \hline
    \hline
    \end{tabular}%
  \label{tab:addlabel}%
\end{table}%

but it returns all the time the errors:

I don't really understand. Can someone explain to me? Thank you in advance!

Answer 1

It seems you don't need multirow, and the code would be simpler without having tp repeat endlessly \bigstrut: the makecell package defines a \makegapedcells which adds some custom padding at the top and bottom of cells. Additionally, the caption package yields a more sensible spacing between captions and tables, when captions are above tables:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{multirow, makecell, caption}

\begin{document}

\begin{table}[htbp]
  \centering\setcellgapes{4pt}\makegapedcells
  \caption{}
    \begin{tabular}{l|l|l|l|l|l|l}
