The use case is unclear, your example does not have *cdkVirtualFor! are you trying to add scrollbar to the virtual scroll which is supposed to display an array of tables? or you want to add a scrollbar to each table inside the virtual scroll?

Show me a working example without the scrollbar library first, then show how it doesn't work with the library.
