The Headers property is one of the accessibility properties designed to make reports accessible to the disabled community when output to HTML or PDF. This property cross-references the ID of the column heading for a particular cell in a table. It is used with the ID property to specify the headings associated with each data cell in a table. With assistive utilities, the column heading can be displayed in a popup or read by a screen reader when the cursor passes over a table cell in report output.

When you output your report in HTML format, the Headers property value
is inserted into the HEADERS
attribute of the TD
tag.
This functionality is not directly supported by PDF. The Oracle Reports PDF driver creates additional information to create an effect similar to the HTML functionality.
If your headers are data-driven (for example, in a matrix report) you can use lexical references to produce unique headers.
