How to prevent theme from styling data tables?-CodePudding

When using a theme for an html output, such as LUX, and creating tables with DT's datatable function, the theme stylizes the output tables, including capitalizing the column names.

Here is the Yaml

---
title: "Untitled"
format: html
editor: visual
theme: LUX
---

And here is an example

library(DT)

datatable(head(iris), extensions = 'Buttons', caption = "Companies Summary",options=list(
  dom = 'Bfrtip',
  buttons = c('csv', 'excel'),
  initComplete = JS(
    "function(settings, json) {",
    "$(this.api().table().container()).css({'font-size': '70%'});","}")))
