Loosen td line-height (1.32 → 1.5) so multi-line cells (long error strings, 200+ char cells) breathe. 2. Header pop: smaller, uppercase, letter-spaced, muted — clear hierarchy vs. body cells (was indistinguishable). 3. First-column emphasis: bolder weight + strong color so the row's anchor (Field name, HTTP code, Method) stands out. 4. Drop inter-column vertical hairlines: horizontal hairlines + zebra already separate rows; verticals add noise without aiding scanning. (Borders OR striping — not both.) 5. Sticky header for long tables (≥ 13 rows) — keeps column labels visible while scrolling 16-row error tables and 58-row method tables on Keys. ============================================================ */ /* 1.
