Hi Anthony,

The last column is rectangular in order to accommodate the number 10, which
is larger than all other numbers in the grid.

About the changing line widths: could you provide an example of this?

Cheers -- Sjoerd

Weird. It looks like this mail never made it to the forums.

Hi, Sjoerd. Thanks for the suggestion! I wasn't aware of the
ImageSizeAction.
Unfortunately, that doesn't quite seem to work. Here's another example that
illustrates the problem better: 
Pane[Grid[Table[i + j, {i, 0, 5}, {j, 0, 5}], Frame -> All, Background -> {3
->
LightBlue}, ItemStyle -> 10,

Alignment -> {Center, Center}], ImageSize -> 300, ImageSizeAction ->
"ResizeToFit"]
Note that the right-most column is distinctly rectangular. When fiddling
with
your example, I also found that the size action can cause the frame borders
to
change thickness, which is something I'd like to avoid.

Hi Anthony,

Something like this?

Pane[Grid[Table[i + j, {i, 0, 4}, {j, 0, 4}], Frame -> All,
  Background -> {3 -> LightBlue}, ItemStyle -> 24,
  Alignment -> {Center, Center}], ImageSize -> 300,
ImageSizeAction -> "ResizeToFit"]

Cheers -- Sjoerd
