*That works, but then the table is left-justified.  But your other
suggestion table.env = "centering" works*
*with the table centered, which I always want to do anyway.  So it is a
nice hack, that replaces 3 lines of*
*LaTeX code to begin  and one LaTeX line to end, which the Springer tech
support suggested.*

I tried table.env = NULL and NA, and both result in an error message
"unexpected symbol".
But I am happy with "centering", and will ask the kableExtra creator and
maintainer Hao Zhu
if he can make a fix in kableExtra.
