Store rich text in a DataTable?

I construct a DataTable via code from data read from several sources, and some of the text is "rich text".

Is there a way to define a column in a DataTable to be of type Rich Text?

I can't see how to do this..

thanks.

If I'm not wrong, rich text is piece of text with additional symbols for formatting. So it's basically the same text, it's the control that parses it that makes it look "rich".
