Read HTML to data objects

When DataTables reads the table content from an HTML table (rather than an Ajax or Javascript data source), by default it will read the information in the table into an array that DataTables stores internally. Each array element represents a column.

It can be very useful to have DataTables read the information into an object rather than an array, an option that can be triggered using the columns.data initialisation option to define how you want the data to be stored. Typically columns.data is used with Ajax sourced data to tell DataTables where to read data from, but as can be seen here it also tells DataTables where to write the data to.

This ability to store data into an object can be very useful when working with the DataTables API after the table has been initialised.

In the example shown here, the data read from each row in the table is read into a Javascript object with the structure:

{
	"name": "...",
	"position": "...",
	"office": "...",
	"age": "...",
	"start_date": "...",
	"salary": "..."
}

Please note that this feature requires DataTables 1.10.3 or newer.

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

$('#example').DataTable({
	columns: [
		{ data: 'name' },
		{ data: 'position' },
		{ data: 'office' },
		{ data: 'age' },
		{ data: 'start_date' },
		{ data: 'salary' }
	]
});

new DataTable('#example', {
	columns: [
		{ data: 'name' },
		{ data: 'position' },
		{ data: 'office' },
		{ data: 'age' },
		{ data: 'start_date' },
		{ data: 'salary' }
	]
});

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.
