The good news is that it's print.xtable escaping the column names, so
in order to sneak LaTeX-special characters into the document, you just
need to print(xtable(table), sanitize.colnames.function = identity).

The bad news is that inserting a line break into a table cell will take
some effort:

https://stackoverflow.com/questions/3068555/how-to-insert-manual-line-breaks-inside-latex-tables

I think the least cumbersome solution is to specify the width of the
column in the 'align' argument and use '\\newline' for the line break.
