I've come to better solution for getting Jupyter-displayable tables to LaTex. Use kable to create an HTML representation and use kable again to create a LaTex representation. Build a “mimebundle” list with these two representations as elements. Use IRdisplay’s publish_mimebundle function to display. 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)

Surely a table cell's contents is a list of blocks (which can include tables). What about this markdown example (butchered from two of the examples in the manual)?

I’ve successfully converted Jupyter HTML-format simple tables to LaTex-format tables using pandoc.read(raw.text, ‘html’).blocks in a lua filter. The resulting LaTex is \begin(longtable} … That’s okay for simple tables, but longtable does not support nested tables, which I do need.

How to convert to LaTex tabular tables (which supports nested tables) rather than to longtable tables (which does not)? Or is there some other solution to converting nested tables?
