You get the cation to the top of the table with
print( saxtab, caption.placement = "top" )
Formatting the table the way you want can be done like this - I did not manage
to carry the LaTeX math formatting for the row names over ($k$ and $n_k$)but the
rest should be very much what you want:
saxtab <- t( as.data.frame( addmargins( Saxony ) ) )
rownames( saxtab ) <- c( "Males (k)", "Families (n_k)" )
saxtab <- xtable( saxtab, digits = 0,
caption = "Number of male children in 6115 Saxony families of size
12",
align = "l|rrrrrrrrrrrrrr" )
print( saxtab, caption.placement = "top", include.colnames = FALSE,
hline.after = c( NULL, 0, nrow( saxtab ) ) )

\begin{tabular}{l|rrrrrrrrrrrrrr}

7 & 6115 \\
\hline
\end{tabular}
\end{table}
