I am using xtable to produce summary tables of linear models, specifying the output as latex.  If I just run the code in R, I get the correct output.  However, the latex output in the org document contains a lot of “|”s.  I think this is because the header of the table contains some code to make “p > |t|”, where the vertical lines are to indicate “absolute value of t”.  My guess is that when the output is written to the results section, org interprets the “|” signs as an org-table and tries to be helpful by adding more of them to make up the correct number of columns. If I switch off the latex output, and write the xtable to a small .tex file, using xtable.print and then include the file after the code block, the table appears correctly.
I’m using emacs 25.2.

Here’s an example:
