 There is currently a light and dark version of the design system, but more are planned. It will also be possible for users to customize the source colors on a per-app or per-system basis. This means that in the future you will be able to modify the core colors to blend in with your chosen terminal theme.

+## Why doesn't the `DataTable` scroll programmatically?
+
+If scrolling in your `DataTable` is _apparently_ broken, it may be because your `DataTable` is using the default value of `height: auto`.
+This means that the table will be sized to fit its rows without scrolling, which may cause the *container* (typically the screen) to scroll.
+If you would like the table itself to scroll, set the height to something other than `auto`, like `100%`.
