I don't think that this is possible with RMarkdown if you want the table to be in LaTeX style. However, you can easily do this with the xtable package when you write your code in an .Rnw file:

\documentclass{article}
\begin{document}
<<>>=
library("xtable")
df <- data.frame(matrix(1:9, nrow = 3))
colnames(df) <- c("first column", "second $\\frac{1}{2}$",
                  "third column")
@

print(xtable(df), floating = TRUE,
      sanitize.colnames.function = identity, type = "latex")
@
\end{document}
