This tag defines the body of the HTML document. The "visible" part of an HTML document is contained between the <body> and </body> tags. The element contains all the contents of an HTML document: texts, visuals, links, tables, lines, etc… It's in this element that the construction in nested tables can begin.

<html lang="en">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<table style="width:100%; margin:0px auto;" align="center" role="presentation" border="0" cellspacing="0" cellpadding="0">
      <td> </td>

A question?
