In some tables you might wish to have some content generated automatically. This can be done in a number of ways: columns.render for content that is dynamic (i.e. based upon the row's data) columns.defaultContent for static content (i.e. simple strings) This examples shows the use of columns.defaultContent to create a button element in the last column of the table. A simple click event listener is used to watch for clicks on a button in the row, and when activated uses the row().data() method to get the data for the row and show a bit of information about it in an alert box. This is a simple use case, but it can be built up to be arbitrarily complex. Note also that the columns.data option for the column has been set to null to indicate that the column has no information contained in the data source object.

When working with large data sources performance is often of primary importance. For this reason DataTables will only create the table tr and td cells when they are drawn on the page. This feature is called deferred rendering and is enabled automatically since DataTables 2. It is rare that you'll want to disable this feature, but if you do need to do so (for example you need to guarantee that all nodes are available for form submission or similar) this option can be set to false as shown in this example. You won't notice any performance difference with just the standard DataTables data set, but for tens of thousands of rows it can make a significant difference and we recommend keeping it enabled.

DataTables has the ability to use data from almost any JSON data source through the use of the columns.data option. In its simplest case, it can be used to read arbitrary object properties, but can also be extended to n levels of nested objects / arrays through the use of standard Javascript dotted object notation. Each dot (.) in the columns.data option represents another object level. In this example hr.position refers to the position property of the hr object in the row's data source object, while contact.0 refers to the first element of the contact array. Any number of dots can be used to obtain deeply nested data. The example below shows DataTables reading information for the columns from nested objects and arrays, where the structure of the row's data source in this example is: { "name": "Tiger Nixon", "hr": { "position": "System Architect", "salary": "$3,120", "start_date": "2011/04/25" }, "contact": [ "Edinburgh", "5421" ] }
