There are alternatives to using tables for side-by-side using paragraphs. Simply having one cell for each line, for instance, allows for highlighting green the added lines and red the removed ones, etc.
Also realize that it is not necessarily the duty of Textile (et al) to handle that aspect beyond text formatting. A diff or history-revision view goes beyond the context of the tool. Lastly, I'm not sure paragraphs belong in table cells. You could certainly argue that a paragraph could full well be tabular data, but I find it hard to believe that it fits the bill. (This is speaking on an XHTML 1.0 Strict basis.) So, in that regard, I don't believe that this is an issue. The real reason to use Textile (for instance) is the natural ease of using it for most things we need. Just a thought. M.T.
