Hi Thank you very much for this…………
I did modifications in xforms.js as below and all the advance tools are getting displayed in the editor toolbar.
tinyMCE.init({
theme : "advanced",
mode : "exact",
elements : "editor",
save_callback : "saveContent",
plugins : "table",
theme_advanced_toolbar_location : "top",
theme_advanced_toolbar_align : "left",
theme_advanced_buttons1_add : "fontselect,fontsizeselect",
theme_advanced_buttons2_add : "separator,forecolor,backcolor",
theme_advanced_buttons3_add_before : "tablecontrols,separator",
theme_advanced_disable: "styleselect",
extended_valid_elements : "a[href|target|name],font[face|size|color|style],span[class|align|style]"
});
