Hi

Here is an example with something at hand if you use Sweave.
Using Sweave you can embed the R in a chunk and properly format the headers and sometimes the table.

the D{.}{.}{4.0} requires the use of \usepackage{dcolumn}

\begin{table}[h]
\caption[DNO and \rdate]%
{DNO and \rdate with row totals}%
\label{tab:CW2}%
\centering
\begin{tabular}{p{1.0in} *{7}{D{.}{.}{4.0}}  }
\toprule
\addlinespace[3pt]
% Header
\multicolumn{1}{Measurement} \\
\addlinespace[3pt]
\midrule
\addlinespace[5pt]
%Table2
<<Table2, keep.source=FALSE, results=tex, echo=FALSE>>=

  xx <- addmargins(xx,2)

  print(
  xtable(xx,
         digits = rep(0,8)
         ),
         type    = "latex",
         floating = FALSE,
         tabular.environment = "tabular",
         include.rownames = TRUE,
         include.colnames = FALSE,
         only.contents = TRUE,
         hline.after = NULL
  ) ## xtable

@ % Table2 end
\addlinespace[5pt]
\bottomrule
\end{tabular}
\end{table}

Hi,

You can set the width of the columns the same way you would in any other LaTeX
table, e.g., by setting align to p{width}.
http://www.giss.nasa.gov/tools/latex/ltx-68.html has a good summary of LaTeX
tables that you may find helpful.

Best,
Ista
