Easyui中datagrid自定义rowStyler，鼠标选中高亮及滑过高亮背景色失效

解决办法：设置.datagrid-row-selected .datagrid-row-over, .datagrid-header td .datagrid-header-over样式优先级即可。

.datagrid-row-selected{
    background: #fced89 !important; /*调整优先级,否则会被自定义rowStyler覆盖*/
    color: #000000;
}
.datagrid-row-over,
.datagrid-header td.datagrid-header-over {
    background: #cddbef !important; /*调整优先级,否则会被自定义rowStyler覆盖*/
    color: #000000;
    cursor: default;
}
