The abbr attribute on TH and TD provides a useful technique for providing an
abbreviated column/row header for assistive technology users. 

This technique is well supported by Screen readers.

An example use case is when additional controls are added into the table
header, such as controls to allow sorting of the table column. For example

<TH abbr="Last Name">Last Name<a ...><img ... alt="sort ascending"></a><a
...><img ... alt="sort ascending"></a></TH>

When reading through the first row of the table a screen reader will read the
links to enable sorting but when reading the body of the table and moving from
column to column a screen reader user will not be bothered by the repetitive
sort ascending and sort descending links.

This technique is frequently used.
