5.6 Provide abbreviations for header labels

Use the abbr attribute in the <th> tag to provide a shortened version of the table header. For example, a header on a column which reads "Percentage growth of internet usage" could be abbreviated to simply, "growth".

Users of screen readers or audio browsers find listening to the content of long and complex tables with long header names cumbersome and repetitive. Providing meaningful abbreviations reduces repetition and improves reading efficiency.
