How to change the strip color on kableExtra

[shanakap]

The color of the strips are very lite on Kable on Pdf output. So is there a way to change the color on kable_styling(latex_options = "striped")?

Hi, @shanakap, I added a new option stripe_color to kable_styling. Now you can do things like:

kable_styling(kable(...), latex_options = "striped", stripe_color = "red")

Right it only take native LaTeX color codes and those hex HTML codes won't work.

If necessary, I can write a global option to make it easier to use, when I have time.

Also, my current feeling is that for I'd better keep this feature within the LaTeX domain because HTML users can easily change the default bootstrap color by putting a CSS section in their document (https://stackoverflow.com/questions/20825211/bootstrap-table-striped-how-do-i-change-the-stripe-background-colour). However, that will change the stripe color for all tables in the document and it's actually difficult to change the color for only one table. 🤔

Thank you so much for adding this option. I tried to use this by re-installing kableExtra and knitr but get the following error,

Error in pdfTable_styling(kable_input, latex_options = latex_options,  : 
  unused argument (stripe_color = "red")
Calls: <Anonymous> ... freduce -> <Anonymous> -> kable_styling -> pdfTable_styling
In addition: Warning messages:

@shanakap have you installed from github via devtools::install_github("haozhu233/kableExtra")?

Hi @haozhu233 i figured out the issue,
The following code works fine, kable(table, booktabs = T,format = "latex") %>% kable_styling(latex_options = "striped", stripe_color = "red")

but soon as you try to use more option on kable_styling it does not work. ex: kable(table, booktabs = T,format = "latex") %>% kable_styling(latex_options = "striped", stripe_color = "red",row.names = FALSE)

Error is; Error in pdfTable_styling(kable_input, latex_options = latex_options, : unused argument (row.names = FALSE) Calls: <Anonymous> ... freduce -> withVisible -> <Anonymous> -> kable_styling Execution halted

Hi, @shanakap, I think if you want to take off the row names, you should use row.names = FALSE in the kable function. ;)

Thanks for the great feature! Just one comment about:

it only take native LaTeX color codes and those hex HTML codes won't work.

A quick workaround is to (1) convert the HEX color you're interested in to RGB. There are plenty of online tools to do that. Just make sure your final values are within [0,1] by dividing them by 255. (2) define a custom LaTeX color with:

\definecolor{my_color}{rgb}{0.95,0.98,1.00} % replace by your RGB values!

Then that color can be called in R with:

...  %>% kable_styling(stripe_color='my_color')
