Column dynamic width

In these docs (https://tanstack.com/table/v8/docs/framework/react/examples/virtualized-rows) columns resize depending on width, but when I copied entire snippet to my project it doesn't? I'm ending up with what you can see on the screenshot. I'm using same version as in the docs. What I need is table which takes full width with certain columns wider than the rest
