The W3C DOM is publically documented:

http://www.w3.org/TR/DOM-Level-2-HTML/

you will find the properties of a HTML <table> element here:

http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-64060425

So the rows property is what you are looking for which then has a
property length you can check.
As for accessing a certain HTML table that is not different from a
accessing any other certain element, if the table has an id attribute
you can use
var table = document.getEle mentById('table Id')
but of course the DOM has other ways (getElementsByT agName, childNodes,
first/lastSibling) to access nodes.

The table-element has a rows collection which you could find the length
of (the rows collection works as an array).

Example:
<table id="tableId">
<tr><td>Row 1</td></tr>
<tr><td>Row 2</td></tr>
<tr><td>Row 3</td></tr>
</table>
<form><input type="button" value="Count Table Rows"
onclick="alert( document.getEle mentById('table Id').rows.lengt h);"></form>

Note that it only counts the rows in the specified table - not also the
rows of the tables inside the table.

Works in IE5+ and NN6+.
