* Just like the _hidden title numeric sorting_ plug-in, this sorting plug-in
|
|
|
3 |
* will take the information to be sorted on from the title attribute of a span
|
|
|
4 |
* element. The only difference is that it is string based sorting rather than
|
|
|
5 |
* numeric.
|
|
|

*
|
|
|
7 |
* Note that the HTML5 `data-sort` attribute can be [used to supply sorting data
|
|
|
8 |
* to DataTables](//datatables.net/manual/orthogonal-data) and is preferable to
|
|
|
9 |
* using this method, which is therefore marked as deprecated.
