DataTables example Child rows (show extra / detailed information)

The DataTables API has a number of methods available for attaching child rows to a parent row in the DataTable. This can be used to show additional information about a row, useful for cases where you wish to convey more information about a row than there is space for in the host table.

The example below makes use of the row().childDT methods to firstly check if a row is already displayed, and if so hide it (row().child.hide()DT), otherwise show it (row() The content of the child row is, in this example, defined by the formatDetails() function, but you would replace that with whatever you wanted to show the content required, possibly including, for example, an Ajax call to the server to obtain the extra information to show.

Name Position Office Salary
Name Position Office Salary

The Javascript shown below is used to initialise the table shown in this example:

/* Formatting function for row details - modify as you need */ function format ( d ) { // `d` is the original data object for the row return '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+ '<tr>'+ '<td>Full name:</td>'+ '<td>''</td>'+ '</tr>'+ '<tr>'+ '<td>Extension number:</td>'+ '<td>'+d.extn+'</td>'+ '</tr>'+ '<tr>'+ '<td>Extra info:</td>'+ '<td>And any further details here (images etc)...</td>'+ '</tr>'+ '</table>'; } $(document).ready(function() { var table = $('#example').DataTable( { "ajax": "../ajax/data/objects.txt", "columns": [ { "className": 'details-control', "orderable": false, "data": null, "defaultContent": '' }, { "data": "name" }, { "data": "position" }, { "data": "office" }, { "data": "salary" } ], "order": [[1, 'asc']] } ); // Add event listener for opening and closing details $('#example tbody').on('click', 'td.details-control', function () { var tr = $(this).closest('tr'); var row = table.row( tr ); if ( row.child.isShown() ) { // This row is already open - close it row.child.hide(); tr.removeClass('shown'); } else { // Open this row row.child( format( ).show(); tr.addClass('shown'); } } ); } );

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:

td.details-control { background: url('../resources/details_open.png') no-repeat center center; cursor: pointer; } tr.shown td.details-control { background: url('../resources/details_close.png') no-repeat center center; }

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.
