Abstract
An apparatus, program product and method support the automated conversion of a table formatted in a CALS-compatible format to an HTML-compatible format, e.g., for use by presentation of the table by a screen reader or other application requiring knowledge of what headers apply to a given cell in a table. A table may be converted from a CALS-compatible format to an HTML-compatible format by assigning an identifier to each header cell in the table, in particular by embedding the identifier in an HTML identifier attribute for such header cell. Then, for each non-header cell in the table, any overlapping header cells therefor may be detected, and the identifier for any detected overlapping header cell may be embedded in an HTML headers attribute for such non-header cell.
