VibeUI

Data Grid

Cell Validation

A grid that validates in place: the error sits under the value itself, the field carries aria-invalid and a link to the message, and saving is blocked until it is fixed.

  2. 2. Write to your agent in your own words and drop the link into the sentence.
  3. 3. The agent opens the link and installs the component from the registry.

# Install and place "datagrid-022" (Cell Validation) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/datagrid-022.json

Registry item: https://vibeui.ru/r/datagrid-022.json
Installs to: components/vibeui/datagrid-022.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A grid that validates in place: the error sits under the value itself, the field carries aria-invalid and a link to the message, and saving is blocked until it is fixed.

A grid with in-place cell validation: aria-invalid, the error under the value and a blocked save. Zero dependencies, one file.

## 3. How to use it
import { Datagrid022 } from "@/components/vibeui/datagrid-022"

<Datagrid022 caption="Timesheet check" maxHours={160} />

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-datagrid-022-* palette — do not swap it for your theme tokens
- the aria-invalid and aria-describedby pair: a red border alone tells a screen reader nothing
- the error text beside the field rather than in a summary on top — otherwise the broken cell is unclear
- the reserved line under the message: without it an appearing error shifts the neighbouring rows
- blocking the save while errors remain, or the form leaves knowingly broken
- top-aligned cells: a cell with an error would otherwise skew the whole row

## 6. You may change
- the line under the toolbar through caption
- the upper bound on hours through maxHours
- the timesheet content through rows
- the accent color through accent

## 7. Rules
- The email check is a simple expression: for a production form rely on a confirmation letter.
- Errors are computed on every render — memoise them once you reach hundreds of rows.
- The initial data deliberately holds three errors so the state is visible in the catalog; start clean in production.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/datagrid-022.json
https://vibeui.ru/r/datagrid-022.json

Компонент самодостаточен: один файл, без зависимостей, палитра в --vibeui-datagrid-022-*. Клиентский: значения лежат в состоянии, проверка считается на каждом рендере, useId даёт стабильные идентификаторы для aria-describedby. Поле с ошибкой получает aria-invalid и ссылку на текст ошибки — одна красная рамка скринридеру ничего не сообщает. Под каждой ячейкой зарезервирована строка высотой с сообщение, поэтому появление ошибки не двигает соседние строки. Кнопка сохранения выключена, пока ошибки есть, а их число объявлено role=status. Ячейки выровнены по верхнему краю: иначе строка с ошибкой перекашивает соседей.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

"use client"

import { useId, useState } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Datagrid022Row = {
  id: string
  employee: string
  email: string
  rate: string
  hours: string
}

export type Datagrid022Props = Omit<
  ComponentPropsWithoutRef<"section">,
  "children"
> & {
  rows?: Datagrid022Row[]
  caption?: string
  maxHours?: number
  accent?: string
}

// Идея компонента: ошибка живёт в той же ячейке, что и значение, а не в
// сводке над таблицей. Поле помечается aria-invalid и связывается с текстом
// ошибки через aria-describedby — иначе красная рамка для скринридера
// ничего не значит. Сохранение блокируется, пока есть хоть одна ошибка,
// и счётчик ошибок объявлен отдельно: пользователь должен знать, сколько
// ячеек ещё надо починить.
