I've very new to word table styles; in fact only really stumbled onto them
today.

I tried my hand at creating a new style to apply alternate row colouring
(grey 15%) but when I applied it, it took out the darker header row
colouring and slid the table a couple of inches off to the right and off the
page. (Word I've found, is very notorious at applying all sorts of hidden
things in the background vs just what you're trying to apply.) Is there a
way to just isolate one particualr effect and apply that, in this case
applying only a 15% grey to alternatve rows only without doing all the rest?
The new stable style was built according to one called "table grid" which I
was hoping was a format that wouldn't change anything else.

Is a table style perhaps the only way to apply alternate row colouring to
all but a header row - 15% grey to alternate rows, 30% grey to header row)?
