Rule n° 239 - Data tables are not replaced by images.

It may be tempting, to go faster, to scan a table in an office document and paste the image into the web page, but this is actually a very bad idea: the contents of this table will neither be indexable by search engines, nor searchable by different users.

  • Give users access to tables that are exploitable by their user agents and that can be reproduced in a way that will always be understandable.


Systematically use the table element and the associated tr, td, th, caption elements to tag data tables, and not images reproducing the table.
