What does thead mean in HTML5

## tag defines the header of the table. must have a tag inside!

Thethead, tfoot, and tbody elements give you the ability to group rows in a table. When you create a table, you probably want to have a header row, some rows with data, and a total row at the bottom. This division gives the browser the ability to support table body scrolling independently of table headers and footers. When long tables are printed, the table header and footer can be printed on each page that contains the table data.

Note: If you use thead, tfoot, and tbody elements, you must use all of them. They appear in the order: thead, tfoot, tbody, so that the browser can render the footer before receiving all the data. You must use these tags inside the table element.

Example:

<table>  <thead>
    <tr>
      <td>THEAD 中的文本</td>
    </tr>  </thead>

  <tfoot>
    <tr>
      <td>TFOOT 中的文本</td>
    </tr>
  </tfoot>

  <tbody>
    <tr>
      <td>TBODY 中的文本</td> 
    </tr>
  </tbody>

</table>
