Shiny 数据表的列标题发生移位
当我运行闪亮的应用程序时，数据表的标题会向左移动。见下表。假设此表位于选项卡A上 当我单击其他选项卡（选项卡B），然后再次单击选项卡a时，标题将正确对齐。有关更正的标题，请参见下文 知道是什么引起的吗？下面是我的代码的简化版本。提前谢谢 ui.RShiny 数据表的列标题发生移位,shiny,dt,Shiny,Dt,当我运行闪亮的应用程序时，数据表的标题会向左移动。见下表。假设此表位于选项卡A上 当我单击其他选项卡（选项卡B），然后再次单击选项卡a时，标题将正确对齐。有关更正的标题，请参见下文 知道是什么引起的吗？下面是我的代码的简化版本。提前谢谢 ui.R library("shinythemes") fluidPage(title = "Segmentation App", theme = shinytheme("spacelab"), navbarPage("Se

最好的解决办法我想出来了
如果我们将autoWidth选项更改为FALSE，标题将正确对齐。我有一个像您这样的长行名表，并且在偏移列名方面也有类似的问题，但是设置autoWidth=FALSE并没有解决问题。我发现这是由scrollX=TRUE引起的。我更改了>ScrollX=FALSE并将数据表包装在带有溢出的div中-x=TRUE以恢复滚动功能：
div(style="overflow-x:auto",renderDataTable({tableName},options=list(scrollX=FALSE))
我也有同样的问题，autoWidth=FALSE
解决了这个问题，但是数据帧使用了所有可用的宽度，请问还有其他解决方案吗？autoWidth
如果需要手动指定列宽，请参见。必须有其他解决方案。
