Question

I use the tablesorter to sort the table, but not all columns, I want to ignore the specific column with the defined class name, eg:

<table class="basicList" cellpadding="0" cellspacing="0"> 
                    <thead> 
                        <tr> 
                            <th class="ck_field"><input type="checkbox" id="check_all" name="check_all" /></th>
                            <th class="col_filter"><a href="#" class="btn_filter">&nbsp;</a></th>
                            <th>Name <span class="sort_indicator">&nbsp;</span></th> 
                        </tr> 
                        <tr class="filter_row"> 
                            <td>&nbsp;</td>
                            <td>&nbsp;</td>
                            <td> <input type="text" id="the_name" name="name" class="filter_field"/></td> 
                        </tr>  
                    </thead>
                </table>

In this example, I don’t want to sort the first two columns.

And I tried:

$(document).ready(function() {

    console.log($(".basicList .col_filter").index());
    console.log($(".basicList .ck_field").index());

    var ck_ignore = $(".basicList .ck_field").index();
    var filter_ignore = $(".basicList .col_filter").index();

    $(".basicList").tablesorter({ widgets: ['zebra'],headers: { 
            //disable the first checkbox cell            
            $ck_ignore: {                
                sorter: false 
            },
            $filter_ignore : {                
                sorter: false 
            }
        }  
    });

Which doesn’t work, how to solve this problem?

Answer 1

Use it like this:

var myHeaders = {};
myHeaders[ck_ignore] = { sorter: false };
myHeaders[filter_ignore] = { sorter: false };

$(".basicList").tablesorter({ widgets: ['zebra'], headers: myHeaders });

Note: if you have more columns with these classes, it will work only for the first occurences.
