# Column Whitespace

I am using the below table and I am getting A LOT of white space between my first column and my models. The space between my models is fine.

\begin{table}\caption{Regression table\label{tab1}}
\begin{center}
\begin{tabular}{l r l r l r l}
\hline
& \multicolumn{2}{c}{Model 1}&\multicolumn{2}{c}{Model 2}&\multicolumn{2}{c}{Model 3}\\
\hline
\hline
Variable 1 & 12.758 & * &  13.822 & *** & 2.123 & *\\
\hline
\textit{*p < 0.05, ** p < 0.01, *** p < 0.001}
\end{tabular}
\end{center}
\end{table}


How can I trim this down so I do not need to use landscape?

Use \multicolum{4}{l}{...} for the last line – egreg Mar 17 '13 at 21:51

@percusse There was an error in my code. I don't see the extra separator – Chris J Mar 17 '13 at 22:08
@egreg Thanks for the response. There was an error in my code, but I do not know what you mean by last line – Chris J Mar 17 '13 at 22:08

The excessive width of the first column arises because the final line of the tabular environment, \textit{*p < 0.05, ** p < 0.01, *** p < 0.001}, is interpreted as belonging to the first column. Use something like \multicolumn{7}{l}{<Content>} instead. (In your initial example, you had 5 columns of data but only 4 columns were specified in the setup of the tabular environment. I see you've updated the code in the meantime to feature 7 columns.)

Separately, I would recommend using the booktabs package to get some good-looking horizontal rules (produced by \toprule, \midrule, and \cmidrule).

\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{table}
\caption{Regression table}\label{tab1}
\centering

\smallskip
\begin{tabular}{@{}l cccccc @{}}
\toprule
& \multicolumn{2}{c}{Model 1}
& \multicolumn{2}{c}{Model 2}
& \multicolumn{2}{c@{}}{Model 3}\\
\cmidrule(lr){2-3} \cmidrule(lr){4-5} \cmidrule(l){6-7}
& Coef. & SE & Coef. & SE & Coef. & SE\\
\midrule
Variable 1 & 12.758 & * &  13.822 & *** & 2.123 & *\\
\midrule[\heavyrulewidth]
\multicolumn{7}{@{}l}{* $p < 0.05$, ** $p < 0.01$, *** $p < 0.001$.}\\
\end{tabular}
\end{table}
\end{document}

Thanks! This is almost exactly what I wanted. How can I get the caption to center across the entire table and not have the preamble "Table 1:". – Chris J Mar 17 '13 at 22:29
@CJ12 - I guess you don't need a "caption" -- in the LaTeX-specific sense of the word -- for your table. Just insert the instruction \multicolumn{7}{c}{Regression table}\ after \begin{tabular}{@{} l cccccc @{}}, and replace \toprule with \midrule[\heavyrulewidth]. Oh, and you can also omit the \smallskip statement. – Mico Mar 17 '13 at 22:41
the only problem is my header is several lines stacked and with caption it worked but with this new method is it possible to stack the header? If I want Regression table and under it 'Attempt B' – Chris J Mar 17 '13 at 23:01
@CJ12: To "stack" (and center-set, right?) two consecutive header lines using the \multicolumn method, you might write \multicolumn{7}{c}{Regression table} \\  \multicolumn{7}{c}{Attempt B} \\  – Mico Mar 18 '13 at 2:19
