There are some people asking how to fix fixed columns need to editable.
The answer is added custom class in the text field such as
<input class="abc" style="width:70px" type="text" id="clientId_0" name="clientId_0" value="">
As Clone DataTable copy the nature of the original table, it gets class abc.
Using these codes,
$('.abc]).on('change', function(){
id = $(this).attr('id').replace('clientId_', ""); //Get Id
$('[id^=clientId_' + id + ']').val($(this).val()); //Put Clone Datatable value to original datatable
});
