It doesn’t make all cells fixed with, it makes all cells’ width equal to each other.
What I expect is, with this option selected, tables’ cells should have same width but slidable on mobile (which is currently makes all cells to same width to fit in screen, which is really ugly thing).
Thus, with this option selected, tables on mobile should be same width as on desktop but with only a portion of it is seen and can be slided to see others parts.
