DT
我有图片网址。我尝试在rmarkdown或闪亮的应用程序中插入图像。我更喜欢---
title: "Untitled"
runtime: shiny
output: html_document
---
df <- data.frame(image = "http://www.ufotm.com/data/attachment/forum/201203/11/110705gf50r55yqcka5ffz.jpg", title = "here is a title")
DT::renderDataTable(df,
escape = FALSE,
rownames = FALSE,
extensions = 'Buttons', options = list(
dom = 'lBfrtip',
buttons = c('copy', 'csv', 'excel', 'pdf', 'print'),
columnDefs = list(list(targets = 1,
data = "img",
render = JS(
'function ( url, type, full) {',
'return '<img height="75%" width="75%" src="'+full[7]+'"/>';',
'}'
)
))
)
)
库,因为我可以下载excel文件。我怎么能这样做?
PS:我想提供excel或pdf文件供我的用户下载。
我尝试使用DataTables Options,找到related question。我尝试了以下代码并显示错误。

您可以使用html代码并使用escape = FALSE
,如下所示:
---
title: "Untitled"
runtime: shiny
output: html_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{r}
df <- data.frame(image = c('<img src="http://www.ufotm.com/data/attachment/forum/201203/11/110705gf50r55yqcka5ffz.jpg" height="52"></img>' ), title = "here is a title")
DT::renderDataTable(df, escape = FALSE)
```
