Also a good idea to write an article re: Table Best Practices.
KISS: Minimize data in each column. Example: If table includes length of service, break it into two columns: Beginning and End. This will not just enable sorting, but also the creation of length of service that will also be sortable.
This is a good example and so is this table. They both have Terms or Terms in Office as one column.
Democratic National Committee#DNC Chairs also need to fix the crappy footnotes within the table. I have all but the footnotes done on my USER page
this is a bit more complicated..President column may spans multiple rows.
