我收到了问题标题中提到的错误。你能帮助我吗？
\begin{table}[htb!]
\centering
\caption{\textit{others criterias : first scenario}} \label{Table2}
\resizebox{0.5\columnwidth}{!}{%
\begin{tabular}{c|ccc|cccc|c}
&\multicolumn{3}{c}{\underline{Instances}}
&\multicolumn{4}{c}{\underline{DPA}}
&&
&Staff &Activities &periods &EA &EB &TG-AV &RV-TD \\ \hline
&3 &72 &10 &477 &47 &178 &1421 \\
\hline
&3 &72 &10 &1087 &34 &207 &1170 \\

建议选择第二种方案。
\documentclass{article}
\usepackage{graphics} % for \resizebox (PS)
\begin{document}
\begin{table}[htb!]
\centering
\caption{\textit{others criterias : first scenario}} \label{Table2}
\resizebox{0.5\columnwidth}{!}{%
\begin{tabular}{c|ccc|cccc|c}
&\multicolumn{3}{c}{\underline{Instances}}
&\multicolumn{4}{c}{\underline{DPA}}
% && % PS
&\\ % PS
&Staff &Activities &periods &EA &EB &TG-AV &RV-TD \\ \hline
&3 &72 &10 &477 &47 &178 &1421 \\
\hline
&3 &72 &10 &1087 &34 &207 &1170 \\
\hline
&3 &72 &10 &1415 &22 &215 &932 \\
\hline
&5 &120 &10 &1925 &1977 &485 &1897 \\
\hline
&5 &120 &10 &457 &552 &216 &1123 \\
\hline
&6 &140 &10 &1605 &1981 &347 &3039 \\
\hline
\end{tabular}%
}
\end{table}
But the first and last column are, in fact, unused. Hence rather:
\begin{table}[htb!]
\centering
\caption{\textit{others criterias : first scenario}} \label{Table2}
\resizebox{0.5\columnwidth}{!}{%
\begin{tabular}{|ccc|cccc|}
\multicolumn{3}{c}{\underline{Instances}}
&\multicolumn{4}{c}{\underline{DPA}}
\\
Staff &Activities &periods &EA &EB &TG-AV &RV-TD \\ \hline
3 &72 &10 &477 &47 &178 &1421 \\
\hline
3 &72 &10 &1087 &34 &207 &1170 \\
\hline
3 &72 &10 &1415 &22 &215 &932 \\
\hline
5 &120 &10 &1925 &1977 &485 &1897 \\
\hline
5 &120 &10 &457 &552 &216 &1123 \\
\hline
6 &140 &10 &1605 &1981 &347 &3039 \\
\hline
\end{tabular}%
}
\end{table}
\end{document}
