One thing I forgot to mention is that within one data table style there
are hierarchical relations between some areas, such as the whole table
has one style, which is the parent of other styles if a feature of
a table style is activated, such as if banded rows are activated there
will be two row style alternating, of which each row style is a child of
the whole table style; or the header row style will be a child of the
whole table style, and the first header cell and last header cell will
each be a child of the header row style.

Class ScStyleSheet provides such relations with SetParent()

Independent of that, if you do
git grep TableStyle sd
you'll find some of the Draw/Impress implementation that may give you
some additional ideas. It is most likely not applicable to Calc though.

If you're interested and plan to work on this I can come up with a more
detailed definition of what properties / region attributes a data table
style for Calc must have and how they relate hierarchically.
