Comparision of the different approaches to the table summary problem

(PS: This table experiments with placing info of non-caption character inside the caption element – to test how this works (since HTML5 opens up for this). The table also uses the axis attribute - don't know if screenreaders make use of it? There are two axises – referred to as categories in the table info inside the caption.)


Table listing the solutions to the non-visual table summary problem. The summary solution is related to the table caption solution and the table info solution of each solution. Categories of the data cells:HTML4 = identical with HTML4 (green background).Change = a change from HTML4 (orange background)
