如果您已经通过编程方式设置了网格，您可以使用“样式”选项来更改网格的布局。

YourGrid = new EnhancedGrid({
                    id: 'YourGridId',
                    store: YourStore,
                    style: "width:500pt;height:200pt;",
                    structure: layoutYourGridsName,
                    rowSelector: '20px',
                    keepSelection: false,
                    plugins: {
                        indirectSelection: IndirectSelectionSettings,
                        filter: Filtersettings,
                        pagination: PaginationSettings,
                        exporter: true
                    }
                });
