I'm trying to remove the first column (RoE) in this example:

```
\documentclass[11pt]{article}
\usepackage{multirow}
\usepackage{tabularx}
\usepackage{booktabs}

\begin{document}

\begin{table}[htbp]
  \centering
  \footnotesize
  \caption{...}
    \makebox[\textwidth][c]{\begin{tabular}{@{\quad} l*{5}{c@{\hspace{8pt}}cp{0.1\tabcolsep}}cc}
    \toprule
          & \multicolumn{2}{c}{RoE} && 
          \multicolumn{2}{c}{RoA} && 
          \multicolumn{2}{c}{GP} && 
          \multicolumn{2}{c}{INV} && 
          \multicolumn{2}{c}{B/P}\\
          \cmidrule{2-3}\cmidrule{5-6}\cmidrule{8-9}\cmidrule{11-12} \cmidrule{14-15}
 &{US} & {EU} && {US} & {EU} && {US} & {EU} && {US} & {EU} && {US} & {EU}  \\
    \midrule
    \multicolumn{3}{l}{Panel A: Boardroom Description} \\
    \midrule
     \multicolumn{1}{l}{Size } & 2.51\% & -3.41\% && -0.63\% & -2.67\% && -4.40\% & -6.11\% && -4.10\% & -0.92\% && 0.05 & 0.18 \\ 
    \end{tabular}}%
  \label{tab:char}%
\end{table}%

\end{document}

```

Unfortunately, I have no clue how I would do this. Can anyone point me in the right direction?

My final table has over 30 rows, so I would like to refrain from manually removing all values that can be found within the table.
