HTML table component or styling in sanity-ui?

You're correct – @sanity/ui doesn't include a dedicated Table component. The library focuses on UI primitives and common interface elements, but a table component isn't part of the current offering.

The available components include primitives like Box, Card, Grid, Flex, Stack, and various form elements (Button, Checkbox, TextInput, etc.), plus higher-level components like Autocomplete, Dialog, Menu, and Tab – but no Table component for displaying tabular data.

If you need table functionality, going with a library like react-table (now @tanstack/react-table) is a solid choice. You can still style it to match your Sanity UI theme by wrapping it in Sanity UI primitives like Card, Box, or Stack, and using the theme tokens for consistent spacing and colors.

For example, you could wrap your react-table in a Sanity UI Card component and use Box elements for cells to maintain visual consistency with the rest of your Sanity Studio or application:

import { Card, Box } from '@sanity/ui'
import { useReactTable } from '@tanstack/react-table'

// Your table implementation wrapped in Sanity UI primitives
