TH description:
The TH tag defines the contents of table header cells. Most browsers make TH cells centered and bold. So if you don’t want those styles you should reset the TH tag in your style sheet.

TH Special Notes:
- The default look and feel of a header cell is usually centered with bold text.
- While you can omit the ending tag, tables are easier to read when they are present, and it gives you better control over style tags.
- When using nested tables, if the TH tags are not closed, the browsers may become confused as to which table elements go with which table.
