Is it required to use thead, tbody and tfoot tags?

Question

Should I really use thead, tbody and tfoot tags every time that I use a table tag? Is it required by the standard or not?

Answer 1

Those tags are not required. It is considered good form to use them if the table is used to represent data, which is what a table should be used for. If a table is used for laying out content they are typically omitted.
