EasyUI 解决datagrid 不能自动伸展的问题

 //开始初始化
            domresize();

            //监听IE窗口的变化
            window.onresize = function () {
                setTimeout(domresize, 300);
            };
            //改变表格宽高
            function domresize() {
                var bodyHeight = $(document).height();
                var bodyWidth = $("#body").width();
                var vHeight = parseInt(bodyHeight, 10) - $('#DivHeard').height();
                vHeight = parseInt(vHeight, 10);
                var vWidth = parseInt(bodyWidth, 10);
                $("#divTable").css("height", vHeight);
                $("#divTable").css("width", vWidth);
                $('#TableBalances').datagrid('resize', {
                    height: vHeight,
                    width: vWidth
                });
            }
