The page was capped at 1100px — a comfortable reading width, and the right
choice for the eight default columns. Now that all 123 fields can be published,
anything past about eight sat behind a horizontal scrollbar on a screen wide
enough to show the lot.
Worse, Windows hides overlay scrollbars until something moves, so a table that
scrolled looked exactly like a table with its right-hand columns missing. That
is what was reported, and the report was reasonable: nothing on screen said
otherwise.
The wrapper grows with its content now, up to the window, and keeps a minimum so
a two-column table does not collapse on a large display. The table sizes to what
its cells need rather than being squeezed to the container first — that squeeze
could wrap a callsign while empty space sat further along the same row. And the
scrollbar is drawn permanently, thin and in the page's own colours.
