解决 table固定行和列，导致滚动条显示

//滚动事件
        var scrollFunc = function (e) {
            e = e || window.event;
                if (e.wheelDelta == 120 || e.detail == -3) {
                    $(‘#cl_freeze‘).scrollTop($(‘#cl_freeze‘).scrollTop()-50);
                    $(‘#t_r_content‘).scrollTop($(‘#cl_freeze‘).scrollTop());
                    tablescroll();
                } else if(e.wheelDelta == -120 || e.detail ==  3 ) {

                   $(‘#cl_freeze‘).scrollTop($(‘#cl_freeze‘).scrollTop()+50);
                    $(‘#t_r_content‘).scrollTop($(‘#cl_freeze‘).scrollTop());
                    tablescroll();
                }
        };

        var cl_freeze = document.getElementById("cl_freeze");
        if (cl_freeze.addEventListener) {
            cl_freeze.addEventListener(‘DOMMouseScroll‘, scrollFunc, false);
        } 
        cl_freeze.onmousewheel = scrollFunc;//IE/Opera/Chrome/Safari
