It seems like makeDataScript() must be provided by classes using this trait. How about adding it as abstract method to this trait?

The property attributes does not exist. Did you maybe forget to declare it?

            $this->ajax['data'] = 'function(data) {
            for (var i = 0, len = data.columns.length; i < len; i++) {

        if ($appendData) {
            $this->ajax['data'] .= $appendData;
        }

        if ($script) {

The expression $script of type string|null is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

            $this->ajax['data'] .= $script;
        }

        $this->ajax['data'] .= '}';
