I've come to better overall solution.  Rather than have pandoc convert HTML 
tables to LaTex tables, I've coded the tables in both HTML and LaTex format 
within the Jupyter notebook.  The HTML representation will be rendered when 
running Jupyter; the LaTex representation will be copied as-is by pandoc 
when converting from Jupyter-format to LaTeX format.

x = data.frame(a=c(1,2,3), b=c(10,20,30), c=c(100,200,300))
x.html = kable(x, format=“html”, escape=FALSE, align=rep(“r”, ncol(x)), 
caption=“This is from HTML”, row.names=FALSE, 
table.attr=“style="white-space: nowrap;"”)
x.latex = kable_styling(latex_options=c(“hold_position”),
kable(x, format=“latex”, escape=FALSE, align=rep(“r”, ncol(x)), 
caption=“This is from LaTex”, row.names=FALSE))
mbx = list(data=list(“text/html”=as.character(x.html), 
“text/latex”=as.character(x.latex)), metadata=NULL)
publish_mimebundle(mbx$data, mbx$metadata)
