I'm very new to LaTeX, and I'm currently waist deep in my first project using it.

I'm trying to right align some text in cells in a table. I am using booktabs, not sure if that changes anything (I'm still trying to figure out how packages work, to be honest).

Here is the output

Here is my code:

\begin{table}[H]
  \begin{center}
    \caption{A comparison of statistics for forest and trailside ash saplings}
    \begin{tabular}{lll}
    \toprule 
    Statistic & Forest & Trailside \\ \midrule
        \rowcolor[gray]{.9} Sample size (trees)       & 243            & 257            \\
        Mean (mm)               & 133.19 & 139.39 \\ 
        \rowcolor[gray]{.9} Median (mm)            & 93             & 100            \\ 
        Standard deviation (mm) & 110.36  & 117.96 \\ 
        \rowcolor[gray]{.9} Standard error (mm)    & 7.08   & 7.36   \\
    95\% Confidence intervals (mm) &  ~ & ~ \\
    \makebox[2.4cm][r] Upper bound & 147.07 & 153.81 \\
    \makebox[2.4cm][r] Lower bound & 119.31 & 124.96 \\
    \bottomrule
    \end{tabular}
  \end{center}
\end{table}

As you can see, I am currently using \makebox[2.4][r] to hack it in, but if there's a more elegant way to accomplish this I'd love to know it.

Welcome at tex.sx! booktabs is a great package, but indeed doesn't meddle with cell alignment. I also changed align to horizontal-alignment :-). –  lockstep Sep 26 '11 at 21:22
    
@lockstep is there anything I need to do to put this as resolved or something like that (I clicked the arrow next to the best answer already)? Thanks for the help! –  Zak Sep 26 '11 at 21:34
    
You've done all you should -- upvoted answers you viewed as helpful, and "accepted" (that's the checkmark) the most helpful one. –  lockstep Sep 26 '11 at 21:43

and welcome to the TeX-LaTeX Stack Exchange! Your table needs very little additional tweeking to achieve your objectives, I believe. In the MWE below, I use the siunitx package (and its column type "S") to align the numbers on the decimal point and the \multicolumn command. Happy TeXing!

\documentclass{article}
\usepackage{booktabs}
\usepackage[table]{xcolor}
\usepackage{siunitx}
\begin{document}
\begin{table}
\centering
\caption{A comparison of statistics for forest and trailside ash saplings}
\smallskip
\sisetup{table-format = 3.2}
\begin{tabular}{lSS}
\toprule 
Statistic & \multicolumn{1}{l}{Forest} & \multicolumn{1}{l}{Trailside} \\ 
\midrule
\rowcolor[gray]{.9} 
Sample size (trees) & 243 & 257\\
Mean (mm)           & 133.19 & 139.39 \\ 
\rowcolor[gray]{.9} Median (mm)  & 93  & 100 \\ 
Standard deviation (mm)          & 110.36  & 117.96 \\ 
\rowcolor[gray]{.9} Standard error (mm)  & 7.08 & 7.36   \\
95\% Confidence intervals (mm) &  ~ & ~ \\
\multicolumn{1}{r}{Upper bound} & 147.07 & 153.81 \\
\multicolumn{1}{r}{Lower bound} & 119.31 & 124.96 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}

Well I'd like to use this for the decimal point stuff, but I get a ton of errors as soon as I add \usepackage{siunitx}... –  Zak Sep 26 '11 at 21:45

@Zak: The siunitx options have somewhat changed from version 1 to 2. Try to upgrade your TeX distribution or replace table-format with tabformat. EDIT: See tex.stackexchange.com/questions/2746/… –  lockstep Sep 26 '11 at 22:03
    
@lockstep Output, code As you can see, the "Forest" and "Trailside" headers are getting messed up. How do I exempt them from "S"? –  Zak Sep 26 '11 at 22:26
    
Disregard that, that was fixed in the example up above by using \multicolumn. –  Zak Sep 26 '11 at 22:35

You can use

\multicolumn{1}{r}{Upper bound}

I suggest you to look at the siunitx package that provides an S column type for correctly output numerical data in tables.

egreg -- you were thinking along the same lines I did with regard to using the siunitx package (I posted before I saw your answer). :-) –  Mico Sep 26 '11 at 21:43
    
@Mico Of course your answer is much more informative than mine. –  egreg Sep 26 '11 at 22:52

Using \multicolumn you can override the column specification for a particular cell:

\documentclass{article}
\usepackage{booktabs}
\usepackage[table]{xcolor}

\begin{document}

\begin{table}
  \centering
    \caption{A comparison of statistics for forest and trailside ash saplings}
    \begin{tabular}{lll}
    \toprule 
    Statistic & Forest & Trailside \\ \midrule
        \rowcolor[gray]{.9} Sample size (trees)       & 243            & 257            \\
        Mean (mm)               & 133.19 & 139.39 \\ 
        \rowcolor[gray]{.9} Median (mm)            & 93             & 100            \\ 
        Standard deviation (mm) & 110.36  & 117.96 \\ 
        \rowcolor[gray]{.9} Standard error (mm)    & 7.08   & 7.36   \\
    95\% Confidence intervals (mm) &  ~ & ~ \\
    \multicolumn{1}{r}{Upper bound} & 147.07 & 153.81 \\
    \multicolumn{1}{r}{Lower bound} & 119.31 & 124.96 \\
    \bottomrule
    \end{tabular}
\end{table}


\end{document}

enter image description here

I would also suggest you to use \centering instead of the center environment to avoid adding extra vertical spacing.

Thank you! Worked great. –  Zak Sep 26 '11 at 21:31
