In order to understand Internet Explorer's DOM (Document Object Model) of a document, it's not enough to examine the source HTML. You need a utility that will parse the HTML file and report the DOM of the document. One such utility is the createTextRange() method. This method creates a textRange object that you can, among other operations, print. The following printRange() function prints the textRange object of the current tip's document:

function printRange() {
  var range = document.body.createTextRange();
  if (range!=null) {
// -->

Try it out. Examine the TABLE's tags. You can see the TBODY tag that is enclosing the table's content. The TBODY tag is part of the DOM, although it is not part of the HTML source.
