> JAWS distinguishes between two types of HTML tables:
> 1. Data tables
> 2. Layout tables
> Data tables should have markup that identify column/row headers (eg. <th>
> elements with scope="col|row") as well as non-empty summary attributes. JAWS
> provides special support for navigating to data tables as well as for
> navigating between cells within data tables.
> Layout tables should not contain any row/column header markup and should
> specify an empty summary attribute. These tables should be completely
> transparent to screen reader end users since they are only used for layout
> purposes.
> Unfortunately JAWS sometimes gets confused and treats some layout tables as
> if they are data tables. This is bad, since this adds "noise" to the screen
> read reader experience - ie. JAWS reports the presence of tables that are not
> interesting to blind users.
> To see this in action, access the following panelFormLayout demo via JAWS:
> http://www.irian.at/trinidad-demo/faces/components/panelFormLayout.jspx
> To see which tables JAWS considers to be data tables, do the following:
> - Hit Insert+F3 to bring up the JAWS "Virtual HTML Featuers" dialog
> - Arrow down to the "Tables List" item and hit Enter
> - JAWS brings up the "Select a Table" dialog, which lists the data tables.
> In the panelFormLayout demo, the only data table in the page is the
> "Attributes" table. However, JAWS incorrectly reports 4 other layout tables
> rendered by the panelFormLayout component as being data tables.
> A simple technique for forcing JAWS to recognize layout tables is to include
> the datatable="0" attribute on the HTML table element. This is non-standard
> attribute that JAWS checks to determine whether a particular HTML table is a
> data/layout table.
> This fix for this bug is to enhance OutputUtils.renderLayoutTableAttributes()
> to render the datatable="0" attribute when in screen reader mode (ie. when
> CoreRenderer.isScreenReaderMode() returns true). This will force JAWS to
> treat any Trinidad-rendered layout tables as layout tables and avoid
> confusion with data tables.
