* Although DataTables' internal numeric sorting works no problem on negative
|
|
* numbers, it does not accept positively signed numbers. This plug-in will
|
|
* sort just such data numerically.

|
|
* @name Fully signed numbers sorting
|
|
* @summary Sort data numerically with a leading `+` symbol (as well as `-`).
