The columns that are fixed in place by FixedColumns take their width from the parent DataTable. As such, the width of the column can be controlled using the
columns.width option.
This example shows the first column being set to width: 20% (note that this is not pixel perfect in a table, the browser will make some
adjustments!), a width that is reflected in the fixed column. Resize the browser window horizontally and you will be able to see that the fixed column retains its
proportional width (again with a small margin dictated by the browser) in the resizing table.
The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
var table = $('#example').DataTable( {
scrollY: "300px",
scrollX: true,
scrollCollapse: true,
paging: false,
columnDefs: [
{ width: '20%', targets: 0 }
],
fixedColumns: true
} );
} );
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:
/* Ensure that the demo table scrolls */
th, td { white-space: nowrap; }
div.dataTables_wrapper {
margin: 0 auto;
}
div.container {
width: 80%;
}
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.
