如何更改 shiny 中的 table 主题

Question

这是我的示例代码：

library(shiny)
library(dplyr)
library(tidyr)
library(ggplot2)
library(gridExtra)
library(shinythemes)
mean_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(sample(1:1000, 1000, replace = T), nrow = 20)
)
names(mean_data)[-1] <- c(paste0("Gene_", 1:50))

sd_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(runif(1000, 5, 10), nrow = 20)
)
names(sd_data)[-1] <- c(paste0("Gene_", 1:50))


###
ui <- fluidPage(
  theme = shinytheme("superhero"),
  pageWithSidebar(
    headerPanel("123"),
    sidebarPanel(
      selectInput(
        "selectGeneSymbol",
        "123:",
        choices = colnames(mean_data)[-1],
        multiple =F,
        width = 400,
        selected = 1
      ),
      
      actionButton(inputId = "plot1", label = "FPKM"),
      bsTooltip(id = "plot1", title = "Please be patient as this calculation process takes some time.", placement = "right", trigger = "hover"),
      actionButton(inputId = "dataTable", label = "dataTable",width=100,class = "btn btn-primary"), 
),
      tags$h6(tags$a(href="https://www.ncbi.nlm.nih.gov/", "link",target = "_top"))
    ),
    mainPanel(
      plotOutput("plot"),
      #uiOutput("all")
      tags$style(HTML("
                    .dataTables_wrapper .dataTables_length, .dataTables_wrapper .dataTables_filter, .dataTables_wrapper .dataTables_info, .dataTables_wrapper .dataTables_processing, .dataTables_wrapper .dataTables_paginate, .dataTables_wrapper .dataTables_paginate .paginate_button.current:hover {

我用的是 superhero shiny 主题。但这导致我的 table 输出看起来不那么适合 table 闪亮的主题。

输出结果是这样的：

只需调整table主题即可。不要关注其他细节。

请给我一些adivce.Vary感激不尽

我也在我的table主题中添加了code.But我不知道如何更改它。

这个问题我自己解决了

虽然修改后的代码让我很困惑。但是我知道如何改变我想改变的地方的颜色。

library(shiny)
library(dplyr)
library(tidyr)
library(ggplot2)
library(gridExtra)
library(shinythemes)
mean_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(sample(1:1000, 1000, replace = T), nrow = 20)
)
names(mean_data)[-1] <- c(paste0("Gene_", 1:50))

sd_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(runif(1000, 5, 10), nrow = 20)
)
names(sd_data)[-1] <- c(paste0("Gene_", 1:50))

如上：

我的代码的重要部分在这里：

tags$style(HTML("

                           }

                    thead {
                    color: #ff7500;
                    }
.dataTables_wrapper .dataTables_length,
.dataTables_wrapper .dataTables_filter,
.dataTables_wrapper .dataTables_info,
.dataTables_wrapper .dataTables_processing,
.dataTables_wrapper .dataTables_paginate {
    color: #ff7500;
}

.dataTables_wrapper .dataTables_paginate .paginate_button {
    color: #ff7500 !important;
}

.dataTables_wrapper .dataTables_paginate .paginate_button.current,
.dataTables_wrapper .dataTables_paginate .paginate_button.current:hover {
