So apparently, Datatables applies custom filters globally, which will TOTALLY screw up your other tables. Recommended workaround is to test each table to ensure it’s the one to apply the filter to…What a joke. Easiest solution is to empty the array of custom filters and rebuild each time...

Custome Filter in Legacy Datatables.js

/**
	 * This function toggles the filter on campaigns with no clicks.
	 * @param  {bool} toggle Boolean value of the toggled checkbox.
	 */
    $scope.toggleShowCampsNoClicks = function(toggle) {
        //    filter the table to show the appropriate entries
        localStorage.setItem('thrivetracker_showCampsNoClicks', toggle);
        $scope.showCampsNoClicks = toggle;

        // custom filter extension for hiding columns with 0
        jQuery.fn.dataTableExt.afnFiltering.push(function(oSettings, aData, iDataIndex) {
            var t = $("#showNoClicks").prop("checked");
            // if we want to show all camps, then just  return true, else only return true
            // for when clicks are greater than 0; aData[3] == clicks
            if (t === true)
                return true;
            else
                return (aData[3] > 0);
        });
        $scope.table.fnDraw();
        // EMPTY OUT THE CUSTOM FILTER BECAUSE DATATABLES IS RETARDED AND MAKES IT GLOBAL INSTEAD OF LOCAL ONLY...
        jQuery.fn.dataTableExt.afnFiltering = [];
    };
