Table header in LaTex

[lepennec]

Hi,

I'm playing with your package and the default for a table with LaTex seems very different from the default in HTM: the header is not separated from the rest by an horizontal line and the table itself does not have a top and bottom line. I have been able to add the first horizontal line with sprinkle(part = "head", border = c("bottom"), border_color = "black" but did not find a way to add the two other lines (other than adding a top line for the header and a bottom line for the last line which is not very satisfactory...)

It's hard to know what you're seeing, but for illustration, this is the HTML table I get using the pure defaults

library(pixiedust)

fit <- lm(mpg ~ wt + qsec + am, data = mtcars)

dust(fit,
     caption = "Linear Model")

The LaTeX table is a very little bit different

Because I think the presentation you are referring to is somewhat common, pixiedust has a standard medley function that can add these lines. The code for it is

library(pixiedust)

fit <- lm(mpg ~ wt + qsec + am, data = mtcars)

dust(fit,
     caption = "Linear Model") %>%
  medley_bw()

And the PDF output is

Note: my YAML content for the PDF output included

---
title: "Examples"
output: pdf_document
header-includes: 
- \usepackage{amssymb} 
- \usepackage{arydshln} 
- \usepackage{caption} 
- \usepackage{graphicx} 
- \usepackage{hhline} 
- \usepackage{longtable} 
- \usepackage{multirow} 
- \usepackage[dvipsnames,table]{xcolor}

If you are getting different HTML output than I am, it's possible you have a CSS file loaded that is influencing your table layout (pixiedust won't override CSS settings unless explicitly instructed to do so). Does that help get the presentation you want?

Thank you for your help. My mistake was coming from the fact that in the vignette there was a

library(pixiedust)
dust(fit)

which produces a table with some borders. Looking at the source, it seems that this indeed due to some (defaullt?) CSS setting in the vignette...

[nutterb]

Oh, I've never noticed that. I will look further into it, because I can see why that would be confusing.

Thanks for pointing it out.

It is indeed a default CSS setting for the vignettes.. but as stated in the vignette vignette:

You can use your own CSS file instead of the built-in style in the markdown package – just set the option markdown.HTML.stylesheet, e.g. options(markdown.HTML.stylesheet = "path/to/a/custom/style.css")

[nutterb]

There's also the option to use

output: 
  rmarkdown::html_vignette:
    css: mystyles.css

(see: http://rmarkdown.rstudio.com/package_vignette_format.html)

The actual CSS for html_vignette

For pixiedust, using a blank CSS file would be optimal.

A css file has been added to the templates. The vignettes will be corrected in the next release. Thanks.
