## What is the current behavior?

Grid 同时使用 `row-span` 与列 `type="expand"` 时,HTML `rowspan` 会把展开行 `<tr>` 算进合并范围,导致合并单元格与展开内容重叠错位。

Issue Number: #4200

## What is the new behavior?

-`useCellSpan` 中于展开行处拆分合并组(`splitRowspanAtExpand`),展开下方相等单元格重新起算
- 展开行保持整行宽度(`colspan = tableColumn.length`),不再被合并单元格覆盖
- 补充 site demo:`span-row-span-with-expand`(含 composition-api)
- 补充单元测试与 E2E:`split-rowspan-at-expand.test.ts``row-span-with-expand.spec.js`
- `.gitignore` 忽略本地 `.pnpm-store/`

## Does this PR introduce a breaking change?

- [ ] Yes
- [x] No

## Other information

- 无展开(`expandeds` 为空)时逻辑早退,不影响既有纯 `row-span` / `span-method` 行为
- PR 标题建议带 E2E 触发:`fix(vue/grid): [grid] split row-span at expand row`

需要的话我可以直接帮你 commit + 开 PR。

Walkthrough

The grid now recalculates row spans when rows expand. New Vue demos, documentation entries, unit tests, and an end-to-end test cover the behavior. The repository also ignores .pnpm-store/.

Changes

Rowspan expansion behavior

Layer / File(s) Summary
Split row spans during expansion
packages/vue/src/grid/src/composable/useCellSpan.ts
The cell-span watcher reacts to expanded-row changes, preserves original row spans, and splits merged cells at expanded rows.
Validate span splitting
packages/vue/src/grid/__tests__/split-rowspan-at-expand.test.ts
Tests cover unchanged spans, missing span configuration, expanded merge boundaries, and custom span coverage.
Document and exercise the grid behavior
examples/sites/demos/pc/app/grid/span/*, examples/sites/demos/pc/app/grid/webdoc/grid-span.js
New Vue demos and documentation show row spans combined with an expand column. Playwright coverage checks row spans, expanded content, and layout overlap.

pnpm store ignore rule

Layer / File(s) Summary
Ignore pnpm store
.gitignore
The ignore rules now exclude .pnpm-store/.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to e5a7a

This change updates Grid row-span handling around expanded rows and adds associated tests and demos. No current merge-blocking risk is identified.

Poem

A rabbit watches row spans grow,
Then sees an expand row show.
Merged cells split with careful grace,
Tests check every boundary place.
“Hop,” says the rabbit, “the layout is right!”

In `@packages/vue/src/grid/src/composable/useCellSpan.ts`:
- Line 243: Align row lookups with the filtered normalTable collection: track
the rows added to normalTable and use that aligned collection instead of
unfiltered tableData for expansion checks and the remainingEqualSpan fallback.
Preserve rendered-cell row alignment when virtual rows precede an expanded
merged group, and add coverage for that scenario.
- Around line 253-254: Update the expanded-row handling in useCellSpan to
preserve the original rowspan/colspan coverage returned by spanMethod, rather
than converting covered { rowspan: 0, colspan: 0 } cells into visible 1x1 cells.
Retain separate original coverage metadata and only restart cells belonging to a
row-span group; add a regression test covering a custom spanMethod that combines
row and column spans.
