FixedColumns operates with DataTables' built-in column visibility options (columns.visible and column().visible()), which columns that are hidden not being shown in the fixed columns. This integration also means that
FixedColumns works well with the column visibility module of the Buttons extension, with columns that are
dynamically shown and hidden updated immediately in the fixed columns.
The example below shows Buttons and FixedColumns working together. Two columns have been fixed on the left-hand-side of the table to show FixedColumns ability to work effortlessly with column visibility.
The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
var table = $('#example').DataTable( {
dom: "Bfrtip",
scrollY: "300px",
scrollX: true,
scrollCollapse: true,
paging: false,
buttons: [ 'colvis' ],
fixedColumns: {
leftColumns: 2
}
} );
} );
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 {
width: 800px;
margin: 0 auto;
}
div.ColVis {
float: left;
}
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.
