Table components: Wider-than-container tables + frozen columns

### Description

In #107, it was planned that our table components (now `Grid`, repeating `Group`, and to some extent `List`) should support lots of columns with a wide scrollable container:

This should probably be an optional parameter that can be set on these components, allowing columns to expand greater widths than the container they're in, with a forced horizontal scrollbar.

In addition, #107 mentioned support for 'frozen columns', where one or more of these columns are 'sticky' and are always displayed when the user is scrolling horizontally.

### Additional Information

- #107

Start by reading the existing Grid, Group, and List table components, then review issue #107 for the earlier requirements. Determine how an optional wide scrollable container and frozen columns should work across these components. Done means the components support the requested horizontal scrolling and sticky-column behavior without forcing it on existing users.
