Note that the code in the column headers has also been updated to include the new data type argument.

For the first two columns, you don’t have to change the function call because both columns contain

strings. The third and fourth columns, however, contain dates and integers, respectively. For each of

these column headers, you must include the data type argument.

Advanced sorting

At this point, you’ve already learned how to sort different data types in the same table in both ascending

and descending order. Unfortunately, it’s very rare that a table contains only regular data types. The

truth is that you will always end up with links, images, or some other sort of HTML in tables; and users

will still want to sort. The most common situation is probably a column that contains icons. Whether the

icon is indicative of something (for instance, an attachment on an e-mail) or just decorative, people want

to be able to sort by it. The previous code does not support such a thing, but that can be fixed.
