Formatted numbers

Sort numbers which are displayed with thousand separators

• Author: Allan Jardine
• Deprecated: This plug-in has been deprecated and replaced with other functionality. Please see the detailed description below for more information.

This plug-in will provide numeric sorting for numeric columns which have extra formatting, such as thousands separators, currency symbols or any other non-numeric data.

By default when a cell is found to have no numeric data its value is sorted numerically as if its value were 0. This could also be altered to be Inifnity or -Infinity as required.

DataTables 1.10+ has formatted number detection 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.

} );
