Shiny 数据表的列标题被移动

Question

当我运行我的 Shiny 应用程序时，我的数据表的标题向左移动。见下文。假设这张表在选项卡 A 上。

当我单击不同的选项卡（选项卡 B）时，标题会正确对齐，然后再次单击选项卡 A。有关更正的标题，请参见下文。

知道是什么原因造成的吗？下面是我的代码的简化版本。提前致谢！

    library("shinythemes")

    fluidPage(title = "Segmentation App", theme = shinytheme("spacelab"),

        navbarPage("Segmentation", id = "allResults",
            tabPanel(value='result_scorecard', title='ScoreCard', 
                     sidebarLayout(
                       sidebarPanel(
                         h4("Select a cluster solution to profile"),
                         width = 3
                       ),

                       mainPanel(
                         verticalLayout(
                           helpText(strong('Summary of Cluster Solutions')),
                           column(DT::dataTableOutput('out_best'), width = 12),                              
                           helpText(strong('ScoreCard Table')),
                           column(DT::dataTableOutput('out_scorecard'), width = 12)

                         )
                       )
                     )
            ),

            tabPanel(value='profile', title='Profile', 
                     verticalLayout(
                         column(DT::dataTableOutput('prop_by_cluster_ind'), width=10)
                      )
            )
        )
    )

    }) 
}

Answer 1

我想到了。

如果我们将 autoWidth 选项更改为 FALSE，标题将正确对齐。
