Well, the direct answer is "no", but then again I did not know the answer to the other question until I Googled it either.

When I do the same for grid.draw, it appears to be a generic function for drawing graphical objects... data frames are not grobs, so you must be doing something to convert it first.

I don't use grid graphics to produce tables... I use knitr::kable or the xtable or tables packages within Rmd or Rnw files.
