thats really damn big for an html file, you're better off just exporting it as a .txt file and then linking to that (txt files will load in the browser)
I tried making a sample page of 2000 rows and 4 columns and tried to import the excel file into dreamweaver and it gave me a message that said "file is too big and would take a very long time to import, please try breaking into multiple pages"
Which seemed really dumb.. but who knows.
