How to merge figures created by Column and Row to export as .esp file?

Hello,
I made a graphic with Column and Row function. But I found that these graphics are not merged together, so I can export them as an intact eps file. The picture below is consisted by three figures.

There is another question: In the left bottom corner, there is no horizontal line and in the right top corner, there is no vertical line. How to add them?

Do you need the row and column labels to be part of the grid? Rather than using Row, Column, Overlay, GraphicsGrid, …, consider using MatrixPlot with Epilog and custom Ticks. Take a look at this for an example.

Okay. It is another way. But is there a way to merge column and row figure?

Will be very difficult to correctly export this figure correctly, too many different substructures that can all have their issues.

Make one Grid is much easier

array = Prepend[Transpose[Prepend[Correlation[Most /@ g[[1]]], h]], 
   Prepend[h, ""]];
Grid[Map[
  If[NumberQ[#],
    Item[Style[NumberForm[#, {3, 2}], 11], 
     Background -> ColorData["Temperature"][#]],
    Item[Style[#, Bold, 11], Background -> White]
    ] &
  , array, {2}],
 Frame -> {All, 
   All, {{1, 1} -> False, {1, 2} -> True, {2, 1} -> True}},
 ItemSize -> {4, 4}, Spacings -> {0, 0}, 
 Alignment -> {Center, Center}]

From your reply, I learned a lot. Thanks.
