Generic HTML Code for All Browsers

Good Evening All,

     I am looking for an HTML code that is compatible with most browsers.  The problem I am having is with tables.  In IE it does not show the borders on each individual cell however in Mozilla Firefox you can see the borders on each individual cell.  I am looking for a code that will NOT show the borders of each cell in most browsers.

    Any ideas? - Any and all assistance is much appreciated.

Thanks in Advance. 

Ok, so I understand what CSS is and I understand the crazy things you can do with CSS however, I am not familiar with CSS.  I did some research applied what I had learned.  My problem now is when I added the code to a cell to show no borders it took away the border around the table as well.  I would like to leave the border around the table however make it disappear for each cell.  Does that make sense?  Any ideas?

Once again any and all assistance is very much appreciated.

Thanks in advance,
Cory
