I am using the jQuery DataTables plugin to sort the table fields. My question is: how do I disable sorting for a particular column? I have tried with the following code, but
There are two ways, one is defined in html when you define table headers
<thead>
<th data-orderable="false"></th>
</thead>
Another way is using javascript, for example, you have table
<table id="datatables">
<thead>
<tr>
<th class="testid input">test id</th>
<th class="testname input">test name</th>
</thead>
</table>
then,
$(document).ready(function() {
$('#datatables').DataTable( {
"columnDefs": [ {
"targets": [ 0], // 0 indicates the first column you define in <thead>
"searchable": false
}
, {
// you can also use name to get the target column
"targets": 'testid', // name is the class you define in <th>
"searchable": false
}
]
}
);
}
);
set class "no-sort" in th of the table then add css .no-sort { pointer-events: none !important; cursor: default !important;background-image: none !important; } by this it will hide the arrow updown and disble event in the head.
If you already have to hide Some columns, like I hide last name column. I just had to concatenate fname , lname , So i made query but hide that column from front end. The modifications in Disable sorting in such situation are :
"aoColumnDefs": [
{ 'bSortable': false, 'aTargets': [ 3 ] },
{
"targets": [ 4 ],
"visible": false,
"searchable": true
}
],
Notice that I had Hiding functionality here
"columnDefs": [
{
"targets": [ 4 ],
"visible": false,
"searchable": true
}
],
Then I merged it into "aoColumnDefs"
This works for me for a single column
$('#example').dataTable( {
"aoColumns": [
{ "bSortable": false
}]});
Here is the answer !
targets
is the column number, it starts from 0
$('#example').dataTable( {
"columnDefs": [
{ "orderable": false, "targets": 0 }
]
} );
What I use is just add a custom attribute in thead td and control sorting by checking that attr value automatically.
So the HTML code will be
<table class="datatables" cellspacing="0px" >
<thead>
<tr>
<td data-bSortable="true">Requirements</td>
<td>Test Cases</td>
<td data-bSortable="true">Automated</td>
<td>Created On</td>
<td>Automated Status</td>
<td>Tags</td>
<td>Action</td>
</tr>
</thead>
<tbody>
<tr>
<td>
And JavaScript for initializing datatables will be (it will dynamically get the sorting information from table iteself ;)
$('.datatables').each(function(){
var bFilter = true;
if($(this).hasClass('nofilter')){
bFilter = false;
}
var columnSort = new Array;
$(this).find('thead tr td').each(function(){
if($(this).attr('data-bSortable') == 'true') {
columnSort.push({ "bSortable": true });
} else {
columnSort.push({ "bSortable": false });
}
});
$(this).dataTable({
"sPaginationType": "full_numbers",
"bFilter": bFilter,
"fnDrawCallback": function( oSettings ) {
},
"aoColumns": columnSort
});
});
