Is there anyway with DataTables to preform a multi-column sort where the secondary column is always sorted DSC irrespective to what sorting direction the primary column is sorted.
{
targets: [ 0 ],
orderData: [ 0, 12 ] //Column 12 needs to always be sorted DSC
}
You could just use orderFixed for sorting like this
$(document).ready( function () {
var table = $('#example').DataTable({
columnDefs: [{
targets: [ 0 ],
orderData: [ 0, 12 ]
}],
orderFixed: [[ 12, "desc" ]]
});
} );
Hope this helps.

I have a problem with jQuery dataTable sorting. It sorts columns in wrong order. For example: I have numbers from 1 to 5, when I click to sort that column it sorts in random order: 4, 1, 3, 5, 2. It's not only with number type. String, date - same problem. I have my data in MySQL database and I get it in json format. My datatable code:
var dataTable = $('#user_data').DataTable({
"processing" : true,
"serverSide" : true,
"order" : [],
"ajax" : {
url:"data_control/orders/fetch.php",
type:"POST"
},
"drawCallback": function( settings ) {
paint();
},
columnDefs: [
{
"orderable": false,
targets: [11, 12, 13, 14]
}
]
});
As I already mentioned - I select my data from database in fetch.php file in JSON format. Any ideas how to solve my problem with sorting?
Thanks!
I write Django app, where I have a base.html template and I defined var table where I declared order by column 0 with 'desc' (look below) So I currently use it some templates, where I extend base.html. But now I need to sort in new template firstly by the second column, and after that by the first column (like this: "order": [1, 0, 'desc'] ). I don't know how I modify this variable without a duplicate code. Could somebody help me?
var table = $('#example').dataTable( {
"columnDefs": [ {
"targets": 0,
"searchable": false,
"order": [0, 'desc'],
"ordering": true,
} ]
} );
In template which extends 'base.html'
<script>
//modify order method
</script>
You can set the ordering using .order() then redraw the table:
table.order( [ 1, 'desc' ], [ 0, 'desc' ] ).draw();
I have created a data table and sorting it according to ASC order, which is working fine. I have an integer value in the column:
Here is my code.
var salaryType = $.fn.dataTable.absoluteOrderNumber([
'TBC',
{ value: 'N/A', position: 'bottom' }
]);
jQuery('#dtTable').DataTable({
"columnDefs": [
{ "type": salaryType, "targets": 2 }
],
"aaSorting": [[2, "asc"]],
});
Now, Few rows are empty in column 2, and the data table is showing NaN.
Is there any way to show N/A instead of NAN with keeping integer field?
I am using jQuery DataTables to style and give functionality to one of my tables:
My Goal
Order by whether or not the type of funding is active or not.. which is what it is doing currently as you can see. Now, I would like to order the Funding column alphabetically.. so my wanted outcome should be:
Funding One
Funding Two
Funding Three
Funding Four
Alpha
Beta
Charlie
Test
test2
Here is what I have so far my datatables script:
var codeFundingTable = $("#Code-Funding-Table").DataTable({
"bPaginate": false,
"bFilter": false,
"aoColumnDefs": [
{ "bSortable": false, "aTargets": [2] },
{ "bSearchable": false, "aTargets": [2] }
],
"columns": [
{ "orderData": [1] },
{ "orderData": [0] }
]
});
So I am first ordering by column 1 (Active, 0-based) then by column 0 (Funding) but it is not doing it alphabetically.
How can I make this happen?
It is a guess since we have no sample data. For example, what is the value of "active" (besides a checkbox is rendered)? But I believe you can just do
var table = $('#example').DataTable({
order: [[1, 'asc'], [0, 'asc']]
})
active column is sorted first, if values is 0 and 1 asc should be used
first column is secondly sorted alpha, with respect of second column order
Here is a demo -> http://jsfiddle.net/0f9Ljfjr/949/ position is sorted first, then name is sorted within each position "type".
Try this on for size
"columns": [
{ "orderData": [1,0] },
https://datatables.net/examples/basic_init/multi_col_sort.html
In my case, what helped me is this.
I used data-order attribute to sort my tables.
data-order="[[ 0, "asc" ], [ 1, "asc" ]]
I am using Data Tables Jquery Plugin. Can anyone help me stopping the table from sorting the first and second columns?
I need the user to be able to click on the other columns and sort them, but when I do it, the first two columns also sort. Can these values be locked and never sort? (I need them static)
For those of you looking to prevent sorting on columns but still allow them to sort when other columns are sorted:
$('#table').dataTable({
// Disable sorting on the first two columns
"aoColumnDefs" : [ {
'bSortable' : false,
'aTargets' : [ 0,1 ]
} ]
});
Or alternatively you can target a class like so:
// Disable sorting based on class
"aoColumnDefs" : [ {
"bSortable" : false,
"aTargets" : [ "disableSort" ]
} ]
Apply the class to the table header not the row.
For the OP, how to make the columns completely static in order to maintain some sort of ranking / index feature every time a column is clicked:
$(document).ready(function() {
$('#example').dataTable( {
"fnDrawCallback": function ( oSettings ) {
/* Need to redo the counters if filtered or sorted */
if ( oSettings.bSorted || oSettings.bFiltered )
{
for ( var i=0, iLen=oSettings.aiDisplay.length ; i<iLen ; i++ )
{
$('td:eq(0)', oSettings.aoData[ oSettings.aiDisplay[i] ].nTr ).html( i+1 );
}
}
},
"aoColumnDefs": [
{ "bSortable": false, "aTargets": [ 0 ] }
],
"aaSorting": [[ 1, 'asc' ]]
} );
} );
