I am using LyX 2.3.6 with TeXLive 2020. I create and print a dataframe using kableExtra - the contents of my table float follow:
<<results = "asis",echo = F, warning = FALSE, tidy=FALSE>>=
library(dplyr)
library(kableExtra)

If I exclude the column_spec statement, this produces a table with no problem at all. As soon as I include the column_spec statement, I get a number of Undefined control sequence errors with the description
...p{8em}>{centeringarraybackslash}p{8em}}
The control sequence at the end of the top line
of your error message was never def'ed. If you have
misspelled it (e.g., `hobx'), type `I' and the correct
spelling (e.g., `Ihbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
In addition, the first column is now centered, and I see the string "ccccc" above the table. I have looked through the log file, and hunted high and low for the cause of the error, upto and including recreating the file. The fact that I am using "Local Currency" and "U.S. Dollar" twice each seems irrelevant - I get the same error if I use four distinct names.
What might be the cause of my errors?
Many thanks in advance
