借助Internet Explorer的开发工具，我发现了哪些CSS类控制了风格Dojo DataGrid标题行。

With the help of Internet Explorer's "Developer Tools," I discovered which CSS classes controlled the styling of the Dojo DataGrid header row.

我需要在.dojoxGridHeader前面添加.tundra，因为.tundra样式表位于层次结构的顶部。

I needed to add ".tundra" in front of .dojoxGridHeader because the .tundra stylesheet is at the top of the hierarchy.

这适用于我：

.tundra .dojoxGridHeader, .tundra .dojoxGridHeader .dojoxGridCell {

    vertical-align: bottom;
    color: #FFFFFF !important;
    background: #530619;
    border-color: #ECE2D8;
    font-weight: bold;
}
