Support for sections in grid

[Victor-Varghese]

Hi,

Anyway to add support for sections ?

I am building a grid that have sticky behaviour (pinned columns with sticky headers). Not sure if there is a way to position headers that span across all columns.

Kind of like sectioned lists in react-native.

code sandbox (similar to what i am using now): https://codesandbox.io/s/react-virtual-grid-sticky-first-row-forked-b64ss?file=/src/index.js:2254-2339

Expected Outcome
