Currently the cell background could only be set to a solid color. The idea is to extend this to gradients.

This should be fixed with Bug 105225 - Color palette cannot be chosen in various places

Question is whether the file format allows gradients. And if that is the case we should go ahead for compatibility. Otherwise I would say out of scope for Calc.

The current ODF 1.3 does not allow gradients for single cells and not for whole tables. That is the same for tables in Writer as for tables in Calc. So who wants to work on this, needs to come up with a concept, how to extend the file format, ideally before starting to implement something.

See documented attempt at implementing this feature (for any devs who want a head start): https://www.patreon.com/posts/bug-49177-color-50095922
This provides some insight into what's going on here.

The problem is handled in https://issues.oasis-open.org/browse/OFFICE-4125
and its resolution in the draft of ODF 1.4.

Thanks Regina.
And I guess this also benefits bug 31205 (Calc) and bug 70384 (Writer) because it includes draw:fill-hatch-name ?

Yes, in ODF 1.4, all places where in ODF 1.3 an background-image is usable will allow all kind of the background fills we know from shapes. Those places include page, header, footer, paragraph, section, table cell, table row and table.

For page, header, footer and paragraph it is currently written in extended mode as <loext:graphic-properties> element as child of <style:style> element. In ODF 1.4 it will be a new <style:background-fill> element as child element of <style:paragraph-properties> or of <style:table-cell-properties>, for example.
