Topic: Tinymce Inline editor removing style attribute.

I am applying tinymce inline editor to td of table , that mean my root element is td.The moment it get applied to td , the style attribute of td get removed . I tried using valid_elements attribute as follows :

valid_elements: td[colspan|rowspan|width|height|align|valign|bgcolor|background|bordercolor"
                  + "|scope|style]

But it didn't work.
