Confirmed

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.

Nicolas,

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.

Best,
Ihor
