r - Shiny 的 DT 数据表 使用户只能编辑某些列

Question

一个简单的应用程序:

#
# This is a Shiny web application. You can run the application by clicking
# the 'Run App' button above.

#

library(shiny)

# Define UI for application that draws a histogram
ui <- fluidPage(

    # Application title
    titlePanel("blah"),

    # Sidebar with a slider input for number of bins 
    sidebarLayout(
        sidebarPanel(),

        # Show a plot of the generated distribution
        mainPanel(
            DT::DTOutput('ex_df')
        )
    )
)

# Define server logic required to draw a histogram
server <- function(input, output) {
    
    output$ex_df <- DT::renderDT(data.frame(
        x = 1:10,
        y = 1,
        z = 11:20
    ), 
    
    selection = 'none', editable = 'cell', server = TRUE, rownames = FALSE,
    list(target = 'cell', disable = list(columns = c(1,2)))
    )
}

# Run the application 
shinyApp(ui = ui, server = server)

使用这一行: disable = list(columns = c(1,2) 我打算使第一列和第二列不可编辑。但是，所有列似乎都是可编辑的:

我如何设置它以便只有第 3 列是可编辑的？

Answer 1

根据 DT::datatable() 的文档，editable 参数的结构应该不同:

This argument can also be a list of the form list(target = TARGET,disable = list(columns = INDICES)), where TARGET can be cell, row,column, or all, and INDICES is an integer vector of column indices.

试试 editable = list(target = "column", disable = list(columns = c(1,2))
