# How to get all horizontal Frame lines in Grid, including topmost and bottom-most?

How can I get the option Frame in TextGrid to do all horizontal lines, including top and bottom?

I want:

----
a b
----
c d
----
e f
----

The closest I get is with the following command:

TextGrid[{{a, b}, {c, d}, {e, f}},  Frame -> {{False, False}, All}]


which produces a grid with horizontal lines but misses top and bottom:

a b
----
c d
----
e f

I tried several things, but to no avail.

 TextGrid[{{a,b},{c,d},{e,f}},Dividers->{False,All}]
