Linking to the 'OR' (bash pipe) operator '|' inside a markdown table

[MichaelChirico]

I am trying to translate this \tabular{} entry to {roxygen2}+markdown:

https://github.com/r-lib/bit64/blob/d783d635b95f66191de503fc4a49eee8298c953e/man/bit64-package.Rd#L270

As of now I don't think it's possible using a markdown table. Crucially, the | in this context wants to be interpreted as the markdown table column separator |.

Claude (the other LLMs I've tried are much worse for this domain) suggests replacing | with its HTML-markup equivalent |. That partially works (roxygen manages to correctly do \link[=|.integer64]), but the &; code gets translated through to the Rd.

This StackOverflow Q&A suggests just escaping \|, which is the best so far, but still results in an inexact translation (in the Rd output, the | should not be escaped:

#' | [`\|.integer64`][xor.integer64] | [`\|`][base::Logic] | |

   \code{\link[=xor.integer64]{\|.integer64}} \tab \code{\link[base:Logic]{\|}} \tab  \cr

That \ does translate through to the Rd/HTML output.
