📚 Description

With @select bound, every row gets tabindex="0" and role="button", but the only handler on the row is @click. A keyboard user can focus a row and pressing Enter or Space does nothing.

The row now also listens for keydown.enter.space and calls the same onRowSelect as a click. That handler already calls preventDefault, so Space doesn't scroll the page, and it already returns early when the event comes from a button or a link inside the row, so a selection checkbox or an actions menu keeps its own keys.

role="button" is dropped. It replaced the implicit role="row", and with a selection column axe reports nested-interactive on every row because the checkbox then sits inside something announced as a button. Rows stay focusable through tabindex, so keyboard access is unaffected.

Two tests: an axe run with @select bound, which currently reports one violation per row, and one checking that Enter and Space reach the handler.

📝 Walkthrough

Walkthrough

Selectable table rows no longer use role="button". They retain focusability and support Enter and Space activation. Repeated keyboard events and interactions from nested controls do not select the row. Tests cover accessibility attributes and callback behavior.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to e79e2

The row preserves native checkbox keyboard behavior, but the new contenteditable test does not verify Space, so a future keyboard regression could pass unnoticed.

233-245: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert row focusability and semantics.

row.trigger() dispatches the event directly on the selected element. It does not require the row to be focusable. (v1.test-utils.vuejs.org)

The test would still pass if tabindex="0" were removed. Assert the tabindex value and the absence of role before triggering the keyboard events.

Proposed assertions
     const row = wrapper.find('tbody tr')
+    expect(row.attributes('tabindex')).toBe('0')
+    expect(row.attributes('role')).toBeUndefined()
     await row.trigger('keydown', { key: 'Enter' })

As per coding guidelines, component tests should cover props, slots, and accessibility, following the repository's Vitest and snapshot-testing patterns.

233-248: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Add a nested-control regression test before merging.

This test sends keyboard events only to the <tr>. It does not cover the required native-control behavior. In src/runtime/components/Table.vue, Lines 475-489, onRowSelect skips only button and a. If the selection checkbox is an input, its Space event bubbles to the row, preventDefault() cancels the checkbox toggle, and onSelect runs. Add coverage for a checkbox, button, and link. Update onRowSelect to skip those controls.

233-248: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the keyboard default-action contract.

The current checks focus on onSelect and the checkbox state after an explicit click. They do not prove that Space on the row prevents page scrolling, or that Enter and Space on nested controls leave native behavior unblocked. Separate the keyboard and click assertions. Assert defaultPrevented for the row Space event and defaultPrevented === false for nested controls. Check the checkbox state before the explicit click, or use a native activation event.

This is required by the PR objective to prevent Space scrolling and preserve native keyboard behavior inside rows.

Also applies to: 265-299

@lazerg Don't take it personally, I do my best to get through all the issues and PRs but it's a lot 😅 The direction looks right, happy to get it in if you reopen.

Three things: the listener needs .self (@keydown.self.enter.space), otherwise Enter or Space inside a contenteditable or a USlider thumb in a cell selects the row. The repeat check should come after preventDefault(), right now holding Space scrolls. And I think label belongs in the selector too, clicking a UCheckbox label in a row selects the row instead of toggling it.

🟡 Minor · Cover Space in the contenteditable test. · Table.spec.ts:323-342

test/components/Table.spec.ts:323-342
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Cover Space in the contenteditable test. The row binding handles both Enter and Space through @keydown.self.enter.space. This test dispatches only Enter, so a Space interception or row-selection regression could pass. Add a Space assertion:

const spaceEvent = await triggerKeydown(editable.element, { key: ' ' })
expect(spaceEvent.defaultPrevented).toBe(false)
expect(onSelect).not.toHaveBeenCalled()

I fixed all three in e79e2a7.

I added .self to the keydown listener. A contenteditable or a USlider thumb in a cell now keeps its own Enter and Space.

I moved the repeat check after preventDefault(). Holding Space no longer scrolls.

I added label to the selector. Clicking a UCheckbox label now toggles it instead of selecting the row.

Each point has a test that fails without its fix. 4b0336a adds one more, for Space on the contenteditable case.

One last thing, I'd add .exact so modified keys pass through. Right now Cmd+Enter on a focused row selects it and never reaches a meta_enter shortcut, and Shift+Space gets swallowed too.

@keydown.self.exact.enter.space="onRowSelect($event, row)"

I added .exact in 2e62bbd. Cmd+Enter and Shift+Space now pass through to your own shortcuts instead of selecting the row. A test covers both.
