You could do something like

With[{gap = 1, elemWidth=3, h = 8, w = 7},
mat = RandomInteger[10, {h, w}];
colours = Table[Blend[{Lighter[Blue], Pink}, j/w], {i, h}, {j, w}];
Framed[Grid[
Framed[Pane[#1, Scaled[1]], ImageMargins -> gap,
Background -> #2] &, {mat, colours}, 2], Spacings -> {0, 0},
ItemSize -> elemWidth], FrameMargins -> gap]]

elemWidth is the width of the elements in the Grid and gap the distance
between the lines.
