Problem with Tables

Hi Everyone!
Wanted to start by saying thanks for helping me out 🙂

Anyway, here is my problem.

I created a table in WordPress, and everything is working fine till I preview the page. I was able to use this code to get rid of the borders.
<td style="border: none;"> <table style="border: none;">

It worked good, and got rid of the borders. However, when I preview the page, and I mouse over the table it turns color, and greys out. Is there any way to stop this? Thanks!
