fix: sort in datatable story.

Contributes to #1560

What did you do?

Added a sort function to the story and more documentation tot he story about the need for user's to implement their own search.

Why did you do it?

The current story emits the search events but does not actually sort the data. This is confusing.

Were docs updated if needed?

• [x] Yes

Initial state

After clicking on "name" header

After clicking on "year" heading

After clicking on "year" heading again (descending sort)

After clicking on "year" heading a 3rd time (no sort)

.sort mutate the sorted array, which is global, but doesn't look like an issue. LGTM, @davidnixon 👍
