Whether to detect and insert table structures.
Much as in HTML, tagged PDF documents support table tags.
However where HTML tables are often used for layout, the concept
behind PDF tables is more semantic. The idea is not so much that
the contents are positioned in a certain way, more that the
contents should be read in a particular way.
If this property is set to true, the AccessibilityOperation will
attempt to detect table structures and add appropriate tags.
If your tables are complicated and you require complete control
over the table detection process, you can do this using the
techniques detailed in the AccessiblePDF example project which
comes with ABCpdf.
