<body><!-- Start of document body -->
<table><!-- Table element -->
<tr><!-- Table row element -->
<th colspan="3">Product</th><!-- Table header cell spanning 3 columns -->
</tr><!-- End of table row -->
<tr><!-- Table row element -->
<th headers="product">Productid</th><!-- Table header cell for "Productid" related to "Product" -->
<th headers="product">Productname</th><!-- Table header cell for "Productname" related to "Product" -->
<th headers="product">Productcost</th><!-- Table header cell for "Productcost" related to "Product" -->
</tr><!-- End of table row -->
</table><!-- End of table -->
</body><!-- End of document body -->
</html><!-- End of HTML document -->

Explanation:

This HTML code defines a webpage with a table displaying product information.
The <table> tag creates a table structure.
The <th> tag creates header cells.
The colspan attribute in the first header cell spans three columns.
Each header cell in the second row has the headers attribute, specifying that they are related to the "Product" header cell in the first row.
CSS styling is applied to the table, table header, and table data cells to add a border around them.
