Issue

When rendering with kit2wp() (and also in the Yaml header using output: github_document) the webshot package makes an image out of a dynamic HTML table, whereas the table works just fine with outputting to a html_document.

• Expected Result from knit2wp() with a searchable table: Similar to codebook.html: http://janajarecki.com/codebook.html
• Result on Wordpress with an image from the table: http://janajarecki.com/blog/a-test-post-2/

Minimal Working Example

Create a sample codebook

    library(codebook)       
    library(knitr)                                                             
    new_codebook_rmd() 

Change two chunks of the auto-generated file codebook.Rmd

First Chunk Change:

    ```{r setup, include=FALSE}
    knitr::opts_chunk$set(
      warning = FALSE, # show warnings during codebook generation
      message = FALSE, # show messages during codebook generation
      error = FALSE, # do not interrupt codebook generation in case of errors,
                    # usually better for debugging
      echo = FALSE  # show R code
    )

#### Last Chunk Change
    ```{r codebook}
     compact_codebook(codebook_data)
    ```

Now render the rmd to Wordpress and compare to the normally-rendered HTML output

    # Note need to define Wordpress credentials first
     knitr::knit2wp("codebook.rmd", title = "a test post")

The issue is that in webshot() the table is rendered as image, as pointed out by Ruben Arslan: rubenarslan/codebook#55

Is there anything you can do to avoid this issue?

xfun::session_info('knitr')

r$> xfun::session_info('knitr')

Changing knitr's behavior to generate HTML instead of a static image for the table is easy on my side, but the actual problem is that you'll have to make sure you load the correct JS libraries and CSS for the table on the WordPress site (usually in ```). That can be very tricky if you want to do it really well. We have done it in the rmarkdown package, and it's a little complicated.

Perhaps you are aware of it, but blogdown does support HTML widgets. Since knit2wp() relies on packages that are no longer actively maintained, I'd suggest you consider blogdown: #1866 (comment)
