/**

|
* Sorts columns by any number, ignoring text. This plugin is useful if you have
|
|
* mixed content in a column, but still want to sort by numbers. Any number means
|
|
*
|
|
* - integers, like 42
|
|
* - decimal numbers, like 42.42 / 42,42
|
|
* - signed numbers, like -42.42 / +42.42
|
|
* - scientific numbers, like 42.42e+10
|
|
* - illegal numbers, like 042, which is considered as 42,
|
|
* - currency numbers, like €42,00
|
|
*
|
|
* Plain text is ignored; columns with no recognizable numerical content
|
|
* is pushed to the bottom of the table, both ascending and descending.
