DataTables - sorting data click only on tableheader's text

I am currently working on an ASP.NET MVC application that uses DataTables in the views to be able to sort the table content by clicking on the header.

The customer wants the area that you can click on to sort the data in that column reduced to only the text of the table header.

I'm including an image to show an example.

Example

Currently the blue square is the area that you can click on to sort the data in that column, the customer wants the red square to be the area that you can click on to sort the data.

Here's what the table in the View in Visual Studio looks like:

<table class="table table-hover dataTable" id="areatable">
    <thead>
        <tr>
            <th>
                th1
            </th>
            <th>
                th2
            </th>
            <th>
                th3
            </th>
            <th  data-orderable="false">
                th4
            </th>
        </tr>
    </thead>

    <tbody>
        @foreach (var item in Model)
        {
            <tr>
                <td>
                    @item.Number
                </td>
                <td>
                    @item.Alarm
                </td>
                <td>
                    <!--NotImplemented-->
                </td>           
                <td>
                    @Html.ActionLink("Details", "Index", "", null, null)
                </td>
            </tr>
         }
    </tbody>
</table>

When you navigate to the url in the browser, one table header starts looking like this:

<th class="sorting_asc" 
tabindex="0" 
aria-controls="areatable" 
rowspan="1" 
colspan="1" 
aria-sort="ascending" 
aria-label="th1: activate to sort column descending" 
style="width: 442px;">
    th1
</th>

Here is the JavaScript to initialize DataTables looks like:

function InitDatatables() {
    $('table.dataTable')
        .DataTable({
            "paging": false,
            "ordering": true,
            "info": false,
            "searching": true,
            "language": {
                "search": "Zoeken: ",
                "zeroRecords": "Geen bronnen gevonden."
            }
        });

        // This code is to initially hide the filter/search bar.
        $("div.dataTables_filter").hide();
        $('div.dataTables_filter input').addClass('form-control').css({ width: 'auto', display: 'inline-block' });
        $('div.dataTables_filter label').prop('disabled', true).css({ float: 'left', marginLeft: '14px' });
}

I looked around a little bit and I could not find similar questions.

I have tried wrapping the tableheader's text into [a][/a] tags and then using JQuery to remove 'class', 'aria-sort' and 'aria-label' from the [th][/th] tags and add these to the [a][/a] tags. This wasn't successful because of my lack of experience with JQuery.

Whenever I would manually remove the mentioned attributes from the [th][/th] tags in the browser using inspect element, the attributes would automatically be added back to the [th][/th] tags upon clicking on the table header, I think it's DataTables itself doing this.

Is there some way to achieve what I'm looking for, or to at least make it look like it's working the way as is requested?

Thank you.

We can achieve this by doing two steps basically

  • Remove Event Listener from the target column cell (due to which complete cell is clickable)
  • Add click handler on target span (image in your case).

I have added a fiddle to give you a live example. Simply remove span tag and insert your image instead of span.

$(document).ready( function () {
  var table = $('#example').DataTable();
  
  //Turning Off ALL event listeners for the Name Table Cell
  $(".targetHeaderCell").off();
  
  //Adding cursor class to testSpan and Removing Cursor class from overall header
  $(".targetHeaderCell").css("cursor","default");
  $("#testSpan").css("cursor","pointer");
  var booleanSortCol1 = false;
  
  // Attaching CLICK Event Handler on Name Span
  $("#testSpan").on("click",function(){
    
    if (booleanSortCol1 == false)
            {
                table.order([0, 'desc']).draw();
                booleanSortCol1 = true;
            }
            else
            {
                table.order([0, 'asc']).draw();
                booleanSortCol1 = false;
            }
  
    
  });
  
  
} );
body {
  font: 90%/1.45em "Helvetica Neue", HelveticaNeue, Verdana, Arial, Helvetica, sans-serif;
  margin: 0;
  padding: 0;
  color: #333;
  background-color: #fff;

Use bSortable:false for each column as below:

{"mData": Client,"sClass": "col-md-3 col-lg-3 ", "sTitle": "Client", "bSortable": false}

add span with some class inside th like below:

<th class="col-md-2 col-lg-2 sorting_disabled" rowspan="1" colspan="1" style="width: 105px;" aria-label="Action"><span class="sortClass">Action</span></th>

Code for Sorting manually is here:

var oTable = $('#table-company-manager').dataTable(); //select the table in variable using jquery

$('.sortClass').click(function(e){

e.preventDefault();

oTable.fnSort([ [0,'asc']] );//use asc/desc as you want

});

comment out these lines from datatables.js file in datatable library:-

nTh.removeAttribute('aria-sort');
nTh.removeAttribute('aria-label');
nTh.setAttribute('aria-sort', aaSort[0][1] == "asc" ? "ascending" : "descending");
nTh.setAttribute('aria-label', sTitle + ", " (nextSort == "asc" ? oAria.sSortAscending : oAria.sSortDescending));

or you may refer modified and fully accessibility supported library which will better work for you and fulfill your requirements please refer below link.
