This table has many more records, and so it is split into pages. One of the columns here contains dates (cf_sorTable has no problem sorting dates or times either).
Note that dates (as well as times, numbers, and currencies) are formatted appropriately for your locale. On this page, the locale is set to "English (US)". For more information about locales, see the documentation for the ColdFusion function setLocale().
Note that this example fails in BlueDragon, which prohibits blank values in a numeric column when re-sorting by query-of-queries.
