The problem is partially because of the way `org-table--to-generic-cell'
works. It disallows custom processing of empty table cells unless both
:raw and :backend arguments are supplied to `orgtbl-to-generic'.

The attached patch should fix the issue, though it may be more
reasonable to fix orgtbl-to-generic logic.


Is there a rationale behind bypassing :fmt and :hfmt for empty table
cells in `org-table--to-generic-cell'? In this patch, I have to work
around this using :raw parameter in `orgtbl-to-generic' call. I do not
feel like such workaround should be needed.

Subject: [PATCH] ob-gnuplot: Honour :missing argument

* lisp/ob-gnuplot.el (org-babel-gnuplot-table-to-data): Force applying
`org-babel-gnuplot-quote-tsv-field' to empty table cells when
converting org tables to gnuplot input.  By default,
`orgtbl-to-generic' ignores :fmt for empty table cells.  We need to
set :raw to non-nil AND :backend to non-nil to force custom formatting
of empty table cells.
