Every column table in the classifier now has the same three powers: multi-column
sort, per-column autofilters, and drag-resizable widths. Two of the three tables
were each missing one; the fix is to make the shared seltable the single engine.
- shared/seltable.js: add multi-column sort (click a header to sort; shift/ctrl-
click ADDS a secondary key; asc→desc→off cycle; ▲/▼ + priority indicator) and
self-contained drag-resizable columns (a .seltable__resizer on each title th —
no dependency on the classifier-only resize.js, since the tables tool shares
seltable). New opt-in opts.persistKey persists widths + sort to localStorage.
- By-tracking grid → seltable (target-tree.js): the bespoke merged-cell table is
replaced by a seltable (status badge, original-name preview link, editable
tracking/rev/title inputs, ✕). It inherits sort + autofilter + resize for free.
The Columns ▾ chooser now rebuilds the seltable; widths + sort persist under the
same prefs key. Grid is self-correcting — a column-set change rebuilds on render.
- Worklist (already seltable): gains sort + resize automatically; the derived
Source column is marked non-sortable/non-filterable.
- The Rename-in-place spreadsheet already had all three (sort.js + filter.js +
resize.js) — no change needed there.
- seltable.css: .seltable__resizer / .seltable__sortind / sortable-header cursor.
- tests: seltable multi-sort (header click, shift-add, indicators) + resize
(drag widens + persists via persistKey); the grid's selectors move off the old
.ttable--grid onto .seltable__table. 66 classify + 56 classifier/tables green.
