I created a log page using datatables. the log messages were long . So, I formatted them to 50 characters and added a button to show details of each log. while this works great on desktop but on mobile it gets funky. So, I enabled the responsive option and added columns priority so they are work nice. but 50 characters were too long for the mobile view too. I want to know a way to reformat columns just for the responsive view and keep the 50 character format for desktop as it is.

```
(function () {
var app = angular.module('app');

app.controller('logController', ['$scope', '$filter', '$sce', function ($scope, $filter, $sce) {

    var state = {};

    var init = function () {
        $(document).ready(function () {
            logTable = $('#table_Logs').DataTable({

                serverSide: true,

                    data: function (serverParams) {
                        // replace column index with column names.
                        for (var i = 0; i < serverParams.order.length; i++) {
