The hardcoded widths with fixed values was just flat our broken and
created all kinds of strange artifacts.
But even with this somewhat more idiomatic approach this still isn't
perfect - on wider screens it doesn't shrink back to the minimum column
width. But that seems like a bit of a corner case. Overall this feels
like a huge improvement.
