OK, thanks.  I guess the problem is with mixing the "absolute" listing
of Dividers properties (None, in my case) with the form n-> spec.

However, it seems to be just the "None" that's a problem, since the
following does work as expected:

   Grid[Join[{{"First", "Second", "Third"}}, Partition[Range[6], 3]],
      Dividers -> {{Green, 2 -> Red, 3 -> Red}, {2 -> Blue}}]

It was by analogy with that form that I tried substituting None for Green.

So it still seems that Mathematica has not fully or correctly
implemented all the possibilities of syntax for Dividers.

Note that, in addition to the way you gave (with the leading None
deleted), it would also be OK to use (the slightly redundant):

   Grid[Join[{{"First", "Second", "Third"}}, Partition[Range[6], 3]],
      Dividers -> {{1 -> None, 2 -> Red, 3 -> Red}, {2 -> Blue}}]
