fix(Table): exclude hidden columns from colspan (nuxt/ui@2e8f533)

[IgorShevchik]

Port of nuxt/ui@2e8f533d — first of ten upstream commits in this run, taken alone since the next is a chore(deps) batch with nothing in common.

Five colspan expressions counted all columns while the body rendered only the visible ones — Table.vue:569 already used row.getVisibleCells(). The row body and the colspan were reading different column sets, which is the whole defect: hide a column and every full-width cell was one column too wide, so the <td> overhung the row it was meant to span.

• row.getAllCells() → row.getVisibleCells() — the expanded row
• tableApi.getAllLeafColumns() → getVisibleLeafColumns() — empty, loading, and the two virtualizer padding rows

Applies verbatim; our pre-image has the same five sites and the same two method names, and this fork's naming is not on any changed line.

Coverage was measured per site, and the measurement changed the PR

reverted alone	upstream's test
expanded	2 red
empty	2 red
loading	78 green
the two virtualizer rows	78 green

So three of the five were riding on a test that cannot see them. One assertion added for loading — it reads the count from the same object as empty but through a different branch, so a fix applied to one and not the other would still have passed. It now turns 2 red when reverted alone.

The two virtualizer padding rows stay uncovered, and that is stated rather than glossed. They are aria-hidden spacers that exist only when the virtualizer is active, so reaching them means standing up a virtualizer harness — out of proportion to a one-word change, and upstream has no such test either. Recorded in .sync/log/ so the gap is known rather than rediscovered.

Worth recording how the added assertion nearly went in wrong: it first passed ...props, which carries data. The loading row is a sibling v-else-if of the rows, so it renders only when there are none — the rows mounted instead and the query came back empty. It failed on correct code, which is the good failure mode; a test passing for the wrong reason would not have shown itself.

Bookkeeping

• .sync/nuxt-ui.json — cursor 726e1420 → 2e8f533d, entry with the pending-merge placeholder.
• .sync/dep-parity.json — refreshed at the new cursor; only the cursor line changes.
• .sync/log/2e8f533d….md — the long-form reasoning.

Local gate green: lint · typecheck · build (3.87 MB) · test (347 files, 7865 passed, 6 skipped) · test:module · repl:build.

Still ahead in this run

Nine more upstream commits: two chore(deps) batches, fix(InputNumber), fix(components) for the virtualizer, an upstream release commit, and four docs-only commits.
