The JWebSwing implementation for Data Tables

There is a newer version: 1.2.2.1-jre17

/**
 * 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 `-`).
 *  @author [Allan Jardine](http://sprymedia.co.uk)
 *
 *  @example
 *    $('#example').dataTable( {
 *       columnDefs: [
 *         { type: 'signed-num', targets: 0 }
 *       ]
 *    } );
