Rule n° 238 - Linearising tables used for layout does not impede the understanding of contents

A vocalised page will be read in a linear fashion, in the order in which its content appears in the HTML code. It can happen that the linearisation of the layout tables breaks the meaning of the page.

  • Supply content that is understandable to users whose user agents or technical aids (screen readers) cannot reconstruct the formatting that was initially defined by a table.


Regroup in the same td cell the information which must be vertically associated (do not distribute it in cells placed in successive rows of the table).
