I have several big formatting problems.

1\ I have tables that I have removed the border shading from, and when displayed in the RadRichTextEditor SOME of the tables have outlines, whilst others do not.
2\ There does not seem to be an option to edit table bordershading once imported into the control
3\ Symbols do not come across correctly (I.e. a box I use as a tick box for a paper form)
4\ You cannot move a tables left hand margin

Hi Grayson Mitchell,

Thank you for your feedback about the issues you have stumbled upon. 
To your specific problems:

1. Are you importing a document that has been created in MS Word? We would greatly appreciate it if you could attach a document that is not imported correctly in terms of border colors.
2. Are you using the latest version of RadRichTextBox? If not, you can check out the TableBordersDialog that opens up when you click on the TableBorders item in the context menu in our demo. The table commands group in the context menu appears when you right-click in an already created table.
3. I assume that the symbol you are talking about is a picture that has been inserted in Word. If that is the case, it is probably included in the document using a relative path to its location on your computer or with an absolute URI. Silverlight has a strict cross-domain policy, hence the picture is not visible.
4. You are right about the left-most margin of the table not being moved. This is so because currently tables do not support left-indent as paragraphs do and the table is always located just after the margin. We are planning on introducing a property that will enable tables to be positioned on different offsets from the left margin, most probably for the service pack of Q1.

If that doesn't answer your questions or you have other comments, do not hesitate to get back to us.

Kind regards,
