I'm trying to draw a Grid of characters where some of the characters have Frame lines on 3 sides. For example:
+ +
x | x | x
+---+
x x x
x x x
That's something like a Grid[item = Table[x,{3},{3}]], except with item[[1,2]] = Item[x,FrameStyle->{{White,Black},{Black,Black}}], except that produces a complete box around the x for me.
When the documentation says:
FrameStyle->{{left,right},{bottom,top}}specifies that different sides of a graphics frame should be drawn with different styles.
I fear that the "...of a graphics frame..." part means that this will work for a Plot, but not for a Grid.
Is there a way to style a frame such that I only draw three edges of it? It doesn't have to be pretty--I'm planning on generating the Grid from some data that I have lying around.
