I'd go with Sooraj's method (using a php include). The current method is to use "require instead of include here's detailed instructions in case you need them:
Make the table, copy the html for the table and it's content alone into a plain text file and save it as TheTable.inc (or whatever) put it in a directory on one of your websites like myMainWebSite.com/includes/datalinks.inc or whatever. Then place this code on any web page (as long as it ends with a .php file extension and it is on a server that will run PHP), on any website where you want that table to appear.
PHP Code:
<?php
require_once("http://myMainWebSite.com/includes/datalinks.inc");
?>
If you do this correctly and it doesn't work there is there is one of two problems in play:
1-Your server doesn't run PHP
2-your server allows PHP but doesn't allow "including" files. contact them and they'll give you simple instruction about putting some text in a file and placing it on your server to give yourself permission.
Welcome to the wonderful world of PHP, that was easy wasn't it?
