在DT datatable中使用liveSearch的shinyWidget pickerInput

我想将shinyWidgets中的pickerInputs插入到Shiny应用程序的DT数据表中。但是，当在数据表中呈现时，liveSearch选项不适用。此外，当我在datatable之外有一个单独的pickerInput时（下面取消注解fluidPage（）内的pickerInput行），表内的pickerInputs不会呈现。我很感激你能帮我把这个弄出来。

library(shiny)
library(DT)
library(shinyWidgets)

shinyApp(
  ui = fluidPage(
    # pickerInput(inputId = "test", label = "Test", choices = c("option1", "option2")),
    DT::dataTableOutput("mytable")
  ),
  server = function(input, output, session) {
    df <- data.frame(
      col1 = as.character(pickerInput(
        inputId = "Picker",
        choices = c("option1", "option2", "option3", "zebra"),
        options = pickerOptions(liveSearch = T)
      ))
    )
    output$mytable <- DT::renderDataTable({
      DT::datatable(
        data = df,
        escape = F
      ) 
    })
  }
)

一种解决方案是将DT表直接放到UI中：

library(shiny)
library(DT)
library(shinyWidgets)

df <- data.frame(
  col1 = as.character(pickerInput(
    inputId = "Picker",
    label = "Picker",
    choices = c("option1", "option2", "option3", "zebra"),
    options = pickerOptions(liveSearch = TRUE)
  ))
)

shinyApp(
  ui = fluidPage(
    
    pickerInput(
      inputId = "test", 
      label = "Test", 
      choices = c("option1", "option2"),
      options = pickerOptions(liveSearch = TRUE)
    ),
    
    datatable(
      data = df,
      escape = F
    )
  ),
  server = function(input, output, session) { }
)

请注意，您必须在UI中放置另一个选择器输入（例如"test"），以便加载JavaScript依赖项。如果你不想要这个选择器输入，你可以用一些CSS（display: none;）隐藏它。
