I want to add another column called "N" right before "Range" column for each sample. How to revise my code?
This is my code:
\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{table}[ht]
\centering
\caption{Descriptive Statistics}
\begin{tabular}{@{} l ccc ccc @{}}
\toprule
& \multicolumn{3}{c}{Dyads Sample} & \multicolumn{3}{c}{Committed Sample} \\
\cmidrule(lr){2-4} \cmidrule(l){5-7}
& Range & Mean & Sd & Range & Mean & Sd \\
\midrule
BAA & \{0,1\}\ & 0.362 & & \{0,1\}\ & 0.306 & \\
BAF & \{0,1\}\ & 0.449 & & \{0,1\}\ & 0.388 & \\
Data Science & \{0,1\}\ & 0.550 & & \{0,1\}\ & 0.406 & \\
Life Science & \{0,1\}\ & 0.597 & & \{0,1\}\ & 0.509 & \\
Engineer & \{0,1\}\ & 0.796 & & \{0,1\}\ & 0.864 & \\
Previous Raised & (0,40.0] & 1.096 & 3.030 & (0,10.0] & 1.101 & 1.754 \\
Max Raise & [0.2,27.7] & 2.026 & 2.658 & [0.2,20.0] & 2.947 & 2.947 \\

Patent & \{0,1\}\ & 0.171 & & \{0,1\}\ & 0.161 & \\
Committed & \{0,1\}\ & 0.0188 & & \{0,1\}\ & 1 & \\
Amount (\$K) & [0,350] & 0.273 & 5.154 & [3,350] & 15.408 & 35.627 \\
\midrule
\#Obs & 18,618 & 18,618 & 18,618 & 330 & 330 & 330 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}
