/**
|
|
* Fairly simply, this plug-in will take the data from an API result set
|
|
* and sum it, returning the summed value. The data can come from any data
|
|
* source, including column data, cells or rows.
|
|
*
|
|
* @name sum()
|
|
* @summary Sum the values in a data set.
|
|
* @author [Allan Jardine](http://sprymedia.co.uk)
|
|
* @requires DataTables 1.10+
|
|
*
|
|
* @returns {Number} Summed value
|
|
*
|
|
* @example
|
|
* // Simply get the sum of a column
|
|
* var table = $('#example').DataTable();
|
|
* table.column( 3 ).data().sum();
|
|
*
|
|
* @example
|
|
* // Insert the sum of a column into the columns footer, for the visible
|
|
* // data on each draw
|
|
* $('#example').DataTable( {
|
|
* drawCallback: function () {
|
|
* var api = this.api();
|
|
* api.table().footer().to$().html(
|
|
* api.column( 4, {page:'current'} ).data().sum()
|
|
* );
|
