# Install and place "datagrid-009" (Resizable Columns) 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-009.json

Registry item: https://vibeui.ru/r/datagrid-009.json
Installs to: components/vibeui/datagrid-009.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 with resizable columns: the separator between headers is dragged with the mouse and nudged with the arrow keys.

A grid with draggable column edges and keyboard width control through role=separator. Zero dependencies, one file.

## 3. How to use it
import { Datagrid009 } from "@/components/vibeui/datagrid-009"

<Datagrid009
  caption="Drag the separator between the headers"
  minWidth={120}
/>

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-009-* palette — do not swap it for your theme tokens
- role="separator" with aria-valuenow and arrow keys: without them a column width cannot be set from the keyboard
- setPointerCapture — without it the drag breaks the moment the cursor leaves the header
- table-layout:fixed together with colgroup: otherwise the browser recomputes widths from content
- the lower width bound: a zero-pixel column disappears along with its content
- the grid's own light surface: on the dark catalog card dark text disappears without it

## 6. You may change
- the line under the toolbar through caption
- the lower column width bound through minWidth, in pixels
- the file list through rows
- the accent color through accent

## 7. Rules
- Widths live in component state and reset on reload — persist them yourself if you need them remembered.
- The keyboard step is 16 px: add a modifier for fine tuning, but do not remove the step itself.
- Cell content is clipped with an ellipsis; the full value stays in the title attribute.
- 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-009.json
https://vibeui.ru/r/datagrid-009.json

Компонент самодостаточен: один файл, без зависимостей, палитра в --vibeui-datagrid-009-*. Клиентский: ширины лежат в состоянии, черновик перетаскивания — в ref, чтобы движение указателя не гоняло лишние рендеры. Разделитель — кнопка с role=separator, aria-orientation, aria-valuenow, aria-valuemin и aria-valuemax; стрелки влево и вправо меняют ширину шагом 16 px, поэтому колонку можно настроить без мыши. Захват указателя через setPointerCapture: без него перетаскивание рвётся, стоит курсору выйти за заголовок. Ширины применяются к colgroup при table-layout:fixed, иначе браузер пересчитает их по содержимому. Содержимое ячейки обрезается многоточием, полное значение остаётся в title.

Component source

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

"use client"

import { useRef, useState } from "react"
import type {
  ComponentPropsWithoutRef,
  CSSProperties,
  PointerEvent,
} from "react"

export type Datagrid009Row = {
  file: string
  owner: string
  changed: string
  size: string
}

export type Datagrid009Props = Omit<
  ComponentPropsWithoutRef<"section">,
  "children"
> & {
  rows?: Datagrid009Row[]
  caption?: string
  minWidth?: number
  accent?: string
}

type Key = "file" | "owner" | "changed" | "size"

// Идея компонента: ширину колонки тянут за разделитель между заголовками.
// Разделитель — это role="separator" с aria-valuenow и стрелками на
// клавиатуре: тянуть мышью умеют все сетки, а вот выставить ширину без мыши
// обычно нельзя. Ширины живут в colgroup при table-layout:fixed, поэтому
// перетаскивание не пересчитывает всю таблицу на каждое движение.
