The sortable-list header folded each column's direction triangle into a
2-cell reserve that doubled as the gap to the next column, so an active
arrow sat immediately against — or, for the TRACED lane, flush against —
the following header. Widen the inter-lane gap to 3 cells across both the
header and the value rows (staying aligned), so the triangle keeps a clear
space on each side. The per-column KEY nudge is now the uniform gap.
