Question

I’m using TableSorter and need to disable the sorting on some columns.

I can add options

In my case I need to add the column numbers 1 and 2 below, from a variable, like I did with my_number. 1 and 2 work but not my_number (which is set to 3).

$(document).ready(function() { 
    var my_number = 3;
    $("table").tablesorter({
        headers: { 
            1: { 
                sorter: false 
            }, 
            2: { 
                sorter: false 
            },
            my_number: {
                sorter: false
            },
        } 
    }); 
});

@koskoz gave you the correct answer, so please give him credit. I wanted to show you the full example of how to use it:

$(document).ready(function() {

    var my_headers = {
        1: { sorter: false },
        2: { sorter: false }
    },
    my_number = 3;

    my_headers[my_number] = { sorter : false };

    $("table").tablesorter({
        headers: my_headers
    });

});

And share an alternative with you. I’ve forked a copy of tablesorter which allows you to just add a class name to the header like sorter-false to disable sorting of that column. Check out this demo
