Utilizing the datatables JavaScript library, the R package DT creates visually appealing tables. While I am able to customize the cell formatting using the formatStyle() function, I have not come across a method for styling the column headers. Is there any way to modify the appearance of the table headers, such as adjusting fonts or alignments?
A majority of inquiries concerning DT on Stack Overflow pertain to R Shiny, but my work does not involve R Shiny.
If you want to customize the appearance of column headers in a datatable, you can utilize the "initComplete" function within the "options" parameter to invoke a specific JavaScript code. Below is an example using R code to set the font size of column headers to 12 pixels:
datatable(
iris,
options = list(
initComplete = JS("function(settings, json) {$(this.api().table().header()).css({'font-size' : '12px'});}")
)
)
