The <th> tag defines a header cell in an HTML table. An HTML table has two kinds of cells: header cells, which contain header information (created with the <th> element), and data cells, which contain data (created with the <td> element). The text in "th" elements are bold and centered by default. The text in "td" elements are regular and left-aligned by default.
