table does not appear when using the package formattable() in R 4.1.0 or R 4.0.3 version

Question

I'm trying to use formatable() but I'm not successful. I'm using some examples from the official CRAN documentation, but not even the examples are running.

i try version R 4.1.0 and 4.0.3, but dont worked.

my code exemple:

library(formattable)
formattable(mtcars, list(mpg = color_bar("lightgray", proportion)))

when using the command the column information disappears

Answer 1

Can you provide sessionInfo(), please? I tried to run the code, and it works fine for me.

This is my sessionInfo():

What version of formattable_0.2.1 and R Studio are you using?

Edit 1: It appears that the font is white. Can you try to edit the color of cyl, and see what happens?

formattable(mtcars, list(mpg = color_bar("lightgray", proportion), cyl = color_text("blue", "blue")))

Edit 2: You are using an outdated R Studio version, however, the problem is related to the themes. If you are using custom themes, make sure that these does not set the font in the viewer pane as white.
