class="group"><td colspan="7">'+group+'</td></tr>' ); last = group; } } ); }, "columnDefs": [ { "targets": 0, "visible": false

class name $(document).ready(function () { $('.datatable_tri').dataTable({ 'columnDefs': [ { 'type': 'file-size', 'targets': 1

ajax call in the ColumnDefs? So the circumstance that

serverSide": true, "ajax": "/server_processing.php", "columnDefs": [ {"className": "center", "targets": [0],

Thanks! var table_blah = $('#blah_table').DataTable({ columnDefs:[ {visible:false,targets:10} ], order: [[ 10, 'asc'

allow either stateSave or columnDefs (to hide a column)

on the table using columnDefs - but it's not working.

That worked! I didn't know I could put the javascript directly attached to the data. Thank you so much!

:) to bigger picture We have app where we searching data base on gps position.. like find me this type of data (enquiry) in London by 15 km max in this time frame. You get list of record which are in this area. But every record can has own list of available categories which are also calculate by gps and i need there the distance of which is this record far from. Now i have 4 and each must find them mainly by gps. Example.... You require in some location accommodation, with time frame and price... our role is find the reservations, free flats, etc for this record in onw distance defined by client.. This mean each record in list has gps and from gps are calculated related subrecords. Do this in one big response is time consuming... this is why i need show the list of records (enquiries) first and after row by row i will additionaly calculate the relate subdata for each row. Sorry for English Miky

Yes the live DOM sorting works as the example describes. But in order to answer exactly for the given example the working code is: $(document).ready(function() { var table = $('#example').DataTable( { columns: [ { orderDataType: 'dom-text', type: 'string' }, null, null ], } ); } ); Or here: https://jsfiddle.net/xe3uvs14/22/ Thank you for the quick and easy to understand response.
