如何在单元格中嵌入图像，使用DT, R和闪亮的表

How can I embed an image in a cell that is generated using the DT package so that it is displayed in an app using shiny?

如何在使用DT包生成的单元格中嵌入图像，使其在应用程序中使用闪亮显示?

My example is based of this question R shiny: How do I put local images in shiny tables

我的例子基于这个问题R闪亮:如何将本地图像放在闪亮的表中

The example code below doesn't display the image, but rather just the url.

下面的示例代码不显示图像，而是显示url。

# ui.R
require(shiny)
library(DT)

shinyUI(
  DT::dataTableOutput('mytable')
)

# Server.R
library(shiny)
library(DT)


dat <- data.frame(
  country = c('USA', 'China'),
  flag = c('<img src="test.png" height="52"></img>',
           '<img src="http://upload.wikimedia.org/wikipedia/commons/thumb/f/fa/Flag_of_the_People%27s_Republic_of_China.svg/200px-Flag_of_the_People%27s_Republic_of_China.svg.png" height="52"></img>'
           )
)

shinyServer(function(input, output){
  output$mytable <- DT::renderDataTable({

    DT::datatable(dat)
  })
})

You can use the escape = FALSE in your DT call, as per: https://rstudio.github.io/DT/#escaping-table-content

您可以在您的DT调用中使用escape = FALSE，如:https://rstudio.github.io/dt/# escapingtable -content。

# ui.R
require(shiny)
library(DT)

shinyUI(
  DT::dataTableOutput('mytable')
)

# Server.R
library(shiny)
library(DT)


dat <- data.frame(
  country = c('USA', 'China'),
  flag = c('<img src="test.png" height="52"></img>',
           '<img src="http://upload.wikimedia.org/wikipedia/commons/thumb/f/fa/Flag_of_the_People%27s_Republic_of_China.svg/200px-Flag_of_the_People%27s_Republic_of_China.svg.png" height="52"></img>'
           )
)

shinyServer(function(input, output){
  output$mytable <- DT::renderDataTable({

    DT::datatable(dat, escape = FALSE) # HERE
  })
})
