how to make selected column only

initComplete: function ()
{
    // Initialize dropdown filter in second column
    this.api().columns([1]).every(function ()
    {
       // ... skipped ...
    });

    // Initialize text filter in first, third and fourth column
    this.api().columns([0, 2, 3]).every(function ()
    {
       // ... skipped ...
    });
}
