Insert Grid - plugin

I have installed "Table JX" in my Joomla 1.5 and I have a component that shows Joomla TinyMCE editor in an article of Frontend for all users of my site. Bellow the editor appears the option "Insert Grid".

If I want to eliminate similar options of others plugins, in my code: "echo $editor->display(...)" that controls the publisher of the Frontend, I add: "array('pagebreak','readmore)".

What word do I have to add so it does not display the "Insert Grid"?

That does not solve the problem.
After trying several solutions, I managed to not see the option "Insert Grid" including in "array" the word "insertgrid".

If I disable the plug-in "Insert Grid" I can not use it.

If I want to use the plug-in, but do not want to see the options under the editor, I have to use the code:

echo $editor-> display('comment','', '500 ', '350', '75 ', '10', array ('pagebreak', 'readmore', 'insertgrid'));

Is it clearer now?
