The waves effect can be applied to any element. To put the waves effect on buttons, you just have to put the class waves-effect on to the buttons. If you want the waves effect to be white instead, add both waves-effect waves-light as classes.

           <a class="waves-effect blue waves-light btn" href="#!">Click Here !</a>
         </td>
