![如何为每个样本添加一列?](https://linux22.com/image/433828/%E5%A6%82%E4%BD%95%E4%B8%BA%E6%AF%8F%E4%B8%AA%E6%A0%B7%E6%9C%AC%E6%B7%BB%E5%8A%A0%E4%B8%80%E5%88%97%EF%BC%9F.png)
我想在每个样本的“Range”列之前添加另一个名为“N”的列。如何修改我的代码?
这是我的代码:
\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 \\
Age & [0,18] & 3.157 & 2.738 & [0,11] & 3.188 & 2.307 \\
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}

如果我正确地理解了您的要求,那么这应该就是您所需要的。
否则请告诉我我做了一些更改:
\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{table}[ht]
\centering
\caption{Descriptive Statistics}
\begin{tabular}{@{} l ccc ccc ccc@{}}
\toprule
& \multicolumn{4}{c}{Dyads Sample} & \multicolumn{4}{c@{}}{Committed Sample} \\
\cmidrule(lr){2-5} \cmidrule(l){6-9}
& N & Range & Mean & Sd & N &Range & Mean & Sd \\
\midrule
BAA && \{0,1\}\ & 0.362 & && \{0,1\}\ & 0.306 & \\
BAF && \{0,1\}\ & 0.449 & && \{0,1\}\ & 0.388 & \\
