I was designing an email editor in my application and used XamRichTextEditor for that purpose. I actually loved it a lot as it has gives html output out of the box which helped me a lot in composing the html based emails.
While designing an email editor, there was a requirement for Inserting/Deleting a column from an existing table in XamRichTextEditor. But since this feature is not yet developed in XamRichTextEditor, I had to drop this feature from my application.
Please include this feature in your next release so that I can utilize it to add into my application.
