推荐答案

您可以使用 GridView 类 (Ext.grid.GridView) 来操作网格.您还可以使用 GridPanel 的 viewConfig 属性.下面是一个例子:

you can use the GridView class (Ext.grid.GridView) to manipulate the user interface of the grid. You can also the viewConfig property of the GridPanel. Here is an example:

viewConfig: {
        //Return CSS class to apply to rows depending upon data values
        getRowClass: function(record, index) {
            var c = record.get('change');
            if (c < 0) {
                return 'price-fall';
            } else if (c > 0) {
                return 'price-rise';
            }
        }
    }

价格下跌和价格上涨是具有相应设置背景颜色的 CSS.例如:

The price-fall and price-rise are CSS that have background colors set accordingly. eg:

.price-fall {
 background-color: #color;
}

.price-rise {
 background-color: #color;
}
