Activating Table Plugin For TinyMCE

Hi There,

I am trying to add the table plugin for TinyMCE. I have downloaded the full version from moxiecode and placed the table folder in /wp-includes/js/tinymce/plugins.

Next I added the following code to the functions.php file from within my theme:

function myplugin_addbuttons() {

   if ( get_user_option('rich_editing') == 'true') {
     add_filter('mce_buttons', 'register_myplugin_button');
   }
}

function register_myplugin_button($buttons) {
   array_push($buttons, "tablecontrol");
   return $buttons;
}

// init process for button control
add_action('init', 'myplugin_addbuttons');

The buttons are still is not showing in the editor. Can someone advise where I am going wrong?

Thanks,

Kris
