This page has a bunch of tips for formatting DT data tables: https://rstudio.github.io/DT/010-style.html

For your specific question, there's the function formatStyle that allows you to set aesthetics based on specific values in the table:

library(DT)
options(DT.options = list(pageLength = 5))
df = as.data.frame(cbind(matrix(round(rnorm(50), 3), 10), sample(0:1, 10, TRUE)))

# style V6 based on values of V6
datatable(df) %>% formatStyle(
    'V6',
    backgroundColor = styleEqual(c(0, 1), c('gray', 'yellow'))
)

# style V1 based on values of V6
datatable(df) %>% formatStyle(
    'V1', 'V6',
    backgroundColor = styleEqual(c(0, 1), c('gray', 'yellow'))
)
