Preamble

This example is almost identical to individual column example and provides the same functionality, but using <select> menus rather than input elements. The API plug-in function fnGetColumnData from Benedikt Forchhammer provides much of the logic processing required, and integration with a table is almost trivial.

One possible interaction chance would be to make use of fnGetColumnData's ability to get filtered data, so you could have the possible filtering values in the select menus to update to only those in the table, rather than all values.

Initialisation code

(function($) {
/*
 * Function: fnGetColumnData
 * Purpose:  Return an array of table values from a particular column.
 * Returns:  array string: 1d data array 
 * Inputs:   object:oSettings - dataTable settings object. This is always the last argument past to the function
 *           int:iColumn - the id of the column to extract the data from
 *           bool:bUnique - optional - if set to false duplicated values are not filtered out
 *           bool:bFiltered - optional - if set to false all the table data is used (not only the filtered)
 *           bool:bIgnoreEmpty - optional - if set to false empty values are not filtered from the result array
 * Author:   Benedikt Forchhammer <b.forchhammer /AT\ mind2.de>
