API plug-in methods
The DataTables API is designed to be fully extensible, with custom functions being very easy to add using the DataTable.Api.register
function.
This function takes two arguments; the first being the name of the method to be added and its chaining hierarchy, and the second the function itself.
This example shows how a sum()
method can easily be added to the API so you can get the sum of a column in a single line:
table.column().data().sum()
. Due to the chaining of the methods, this allows sum()
to very easily give the sum for any selected
column, and to limit the sum to just the current page, filtered data or all pages. This is done using the options for the column()
method and the options for its selectors.
For more information about API plug-ins; creating them and their requirements, please refer to the plug-in development documentation.

The Javascript shown below is used to initialise the table shown in this example:
// Register a `sum` API method with DataTables
DataTable.Api.register('column().data().sum()', function () {
return this.reduce(function (a, b) {
var x = parseFloat(a) || 0;
var y = parseFloat(b) || 0;
return x + y;
});
});
// Init the table and fire off a call to get the hidden nodes.
var table = $('#example').DataTable();
$('#sum-all').on('click', function () {
let text = 'Column sum is: ' + table.column(3).data().sum();
$('#demo-output').append($('<div>').text(text));
});
$('#sum-visible').on('click', function () {
let text =
'Column sum is: ' + table.column(3, { page: 'current' }).data().sum();
$('#demo-output').append($('<div>').text(text));
});
// For demo - adds text to the output box
function addOutput(text) {
let newEl = document.createElement('div');
newEl.textContent = text;
document.querySelector('#demo-output').prepend(newEl);
}
// Register a `sum` API method with DataTables
DataTable.Api.register('column().data().sum()', function () {
return this.reduce(function (a, b) {
let x = parseFloat(a) || 0;
let y = parseFloat(b) || 0;
return x + y;
});
});
// Init the table and fire off a call to get the hidden nodes.
const table = new DataTable('#example');
document.querySelector('#sum-all').addEventListener('click', function () {
addOutput('Column sum is: ' + table.column(3).data().sum());
});
document.querySelector('#sum-visible').addEventListener('click', function () {
addOutput(
'Column sum is: ' + table.column(3, { page: 'current' }).data().sum()
);
});
In addition to the above code, the following Javascript library files are loaded for use in this example:
The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:
This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:
The following CSS library files are loaded for use in this example to provide the styling of the table:
This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.
The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
