How do I format this table in latex?

Question

I have this table from Stata:

EDIT: After taking Mico's suggestion I was able to create the table with the following codes:

\begin{table}[htbp]
\caption{Summary Statistics} \label{tab:1}  
\centering
\setlength\tabcolsep{4.5pt} % default value: 6pt
\begin{tabular}{@{} l l|
         d{2.7} d{1.7} d{2.7} d{2.7} | 
         >{$}r<{$} @{${}={}$} d{4.0} @{}} % 
\multicolumn{2}{@{}l|}{Variable\Bstrut} & \mc{Mean} & \mc{Std.~Dev.} & \mc{Min} & \multicolumn{1}{c|}{Max} & \multicolumn{2}{r@{}}{Observ.}\\
\hline

  & within & & .2759787 & -.6309633 & 1.119037 & T & 8\\[1ex] % extra vertical whitespace
\end{tabular}
\end{table}

However, the problem now is that they're not aligned properly like the original table. How do I do that?

Answer 1

I suggest you use the dcolumn package to align the numeric data on the decimal marker.

\documentclass{article}
\usepackage{dcolumn,caption}
\newcolumntype{d}[1]{D{.}{.}{#1}}
\newcommand\mc[1]{\multicolumn{1}{c}{#1}}

%% define a few struts
%% (from code by Claudio Beccari in TeX and TUG News, Vol. 2, 1993)
\newcommand\Tstrut{\rule{0pt}{2.9ex}}       % "top" strut
\newcommand\Bstrut{\rule[-1.2ex]{0pt}{0pt}} % "bottom" strut
\begin{document}
\begin{table}[htbp]
\caption{Summary Statistics} \label{tab:summ_stats}  
\centering
\setlength\tabcolsep{4.5pt} % default value: 6pt
\begin{tabular}{@{} l l|
         d{2.7} d{1.7} d{2.7} d{2.7} | 
         >{$}r<{$} @{${}={}$} d{4.0} @{}} % 
\multicolumn{2}{@{}l|}{Variable\Bstrut} & \mc{Mean} & \mc{Std.~Dev.} & \mc{Min} & \multicolumn{1}{c|}{Max} & \multicolumn{2}{r@{}}{Observ.}\\
\hline
lwage\Tstrut & overall  & 1.649147  & .5326094 & -3.579079 & 4.05186 & N & 4360\\
 & between & & .3907468 & .3333435 & 3.174173 & n & 545\\
  & within & & .3622636 & -2.467201 & 3.204687 & T & 8\\[1ex] % extra vertical whitespace
educ & overall & 11.76697 & 1.746181 & 3 & 16 & N & 4360\\
etc\\
\end{tabular}
\end{table}
\end{document}

Addendum to address the OP's follow-up request: To make the table look (almost) like it was printed by Stata, (i) use r instead of d column types for the numeric columns, and (ii) switch to a monospaced font, e.g. by modifying the macro \familydefault.

\documentclass{article}
\usepackage{caption}

%% define some typographic struts
%% (from code by Claudio Beccari in TeX and TUG News, Vol. 2, 1993)
\newcommand\Tstrut{\rule{0pt}{2.9ex}}       % "top" strut
\newcommand\Bstrut{\rule[-1.2ex]{0pt}{0pt}} % "bottom" strut

\begin{document}
\begingroup  % localize the redefinition of \familydefault
\renewcommand{\familydefault}{\ttdefault}\selectfont
