If the parameter "sortable=yes" is specified, the template generates invisible text that will cause the output to work in sortable tables, at the cost of adding those words (read-out, audibly) by many screen readers. The benefit is effective, clickable arrows as in "Col 2" below:

Title Col 1 Col 2
Foo 1066 1066
Bar ਅੰ. 1510 1510ਅੰ. 1510
Baz 1956 1956
Jaz ਅੰ. 410 410ਅੰ. 410
