Describe the bug and the steps to reproduce it

https://www.material-react-table.com/docs/guides/column-pinning#apply-absolute-column-widths
Pinned columns don't keep fixed width when using layoutMode: 'grid-no-grow' as written on the guide.

Minimal, Reproducible Example - (Optional, but Recommended)

https://github.com/KevinVandy/material-react-table/blob/v2/apps/material-react-table-docs/examples/enable-column-pinning/sandbox/src/TS.tsx
The problem occurred on my current project.
I tried running this example and the problem was same.

Strangely, on the guide website, the behavior works as expected.
