I just wanted to check first before attempting this.
In a recent project we want to insert specific table html into the tinymce editor.
I can see that in the 'modules > _protected > CMS' folder is a zip file of the cms.
If I extract this and find the 'table.htm' make the changes and zip back up.
Should this change the table html ouput?
That will make you lose the settings on every upgrade. Something like this should still work: http://krompaco.nu/2010/06/replacing-the-tinymce-table-plugin-in-episerver-6/
