How to remove stroke from cells?

Hi!

I have 60 pages worth of tables. I want to remove black strokes appearing on the bottom of some orange filled cells. I use 5 cell styles. One is "no fill, stroke", and other four have "fill (gradients of a single colour), no stroke"

I presume that I need all cells that are not white to have theire cell styles re-applyed.

What would script for something like that look like?

Thanks in advance.
