Display class of variables in a nice neat table in R-markdown using gt or gtsummary

Question

I would like to display a dataframe structure nicely, especially showing column names and class. I want to do something kind of like this:

str(my_df) %>% tbl_summary()

I know that doesn't work, but I thought it would explain what I wanted to do well. There are quite a few images showing class in the table output but I can't find example code anywhere. I've been trying with gtsummary.

Desired output something like so...

Answer 1

You may construct the data that you want to display and use any of the pretty table display library.

data <- setNames(stack(sapply(iris, class))[2:1], c('variable', 'class'))
data

#      variable   class
#1 Sepal.Length numeric
#2  Sepal.Width numeric
#3 Petal.Length numeric
#4  Petal.Width numeric
#5      Species  factor

gt::gt(data)
