Although I agree with the general principles behind Alan's thinking in this area, and appreciate the clarifications which he offers, it remains to be shown that the benefits of the trick which he suggests would outway its disadvantages. For example, the non-breaking spaces could cause havoc in the braille formatting of a document, given the typical maximum line length of 40 characters. So far as the advantages are concerned, the proper formatting of tables in Lynx would indeed be helpful to braille display users, but of limited benefit to those relying upon speech synthesizers, since the spatial aspects of the document can not be conveyed by a screen reader in an intelligible fashion. Of course, the reader might resort to counting spaces and locating columns manually, using the review functions offered by the screen reader, but I doubt that many readers would be inclined to do so. Consequently, I think this is one deficiency, limited to only a single browser, which should not be compensated for in the guidelines. Indeed, as I remember, problems specific to only one browser were ruled out of consideration at an earlier stage of guideline development when it was proposed that tricks should be introduced to avoid certain shortcomings associated with the handling of TITLE and ALT by Microsoft's browser. A trick concerned with the treatment of TR and TD elements by Lynx was also rejected on similar grounds.
