Yes, a background image would work great as fallback for other office suites, 
but not if you want to allow actual editing of backgrounds. At the moment I 
think the only background style sheets supports that is not just an 
image/color is hatches, but gradients would probably not be very hard to 
support too, and there isn't really a way to express that with standard odf.
So the calligra:fill-style-name attribute references a graphic style that is 
used as background for the table cell.

Excel has a couple more vertical alignment options than odf supports (and 
sheets supports them too, although not exposed in the UI), so
we use this extra attribute to store that information. The attribute can be 
either empty or have value "distributed" (and together with the vertical-align 
property that then determines what the actual vertical alignment/distribution 
is).

Again a feature Excel supports that odf doesn't. Extra-short here means that 
the month is only displayed as the first character (not sure how you're 
supposed to distinguish months that start with the same letter, but that's 
what Excel does...)
