How to fix a table's column width on R Shiny using Formattable?

Question

I would like to display the data frame on R Shiny using formattable. However, the solution here doesn't work. https://cran.r-project.org/web/packages/formattable/vignettes/formattable-data-frame.html

scores <- data.frame(id = 1:5,
                    prev_score = c(10, 8, 6, 8, 8),
                     cur_score = c(8, 9, 7, 8, 9),
                     change = c(-2, 1, 1, 0, 1))

width_formatter <- formatter("span",
                               style = x ~ style("width" = '100px'))


formattable(scores, list(width_formatter))

How can I do it? Thanks

Other than the DT solution, as said in the vignette of formattable, you can use elements from formattable with knitr::kable . Then you can use kableExtra to deal with the column width issue.
