* This type-detection plug-in will look at an HTML string from a data cell,
|
|
* strip the HTML tags and then check to see if the remaining data is numeric.
|
|
* If it is, then the data can be sorted numerically with the Numbers with HTML
|
|
* sorting plug-in.
|
|
*
|
|
* DataTables 1.10+ has numeric HTML data type and sorting abilities built-in.
|
|
* As such this plug-in is marked as deprecated, but might be useful when
|
|
* working with old versions of DataTables.

|
* @name Numbers with HTML
|
|
* @summary Detect data which is a mix of HTML and numeric data.
|
|
* @deprecated DataTables 1.10+ has built in support for this data type
