In my shiny app I am using datatable function from DT library to construct a table and want to align columns on center. I can use formatStyle('column', textAlign = 'center') but it affects only column body and not the header. You have to set columnDefs in the argument option of the function datatable . Look the example below library(DT) datatable(head(iris), rownames = FALSE, options = list( columnDefs = list(list(className = 'dt-center', targets = 0:4)) )) OBS. You have to set the target. In the example all the 5 columns are aligned to "center" (targets = 0:4). Finally, note that column

How do I utilize javascript to display the cell value in a tooltip after hovering over a particular cell in a DT::datatable? I decided to hide the long text after a certain width is reached ( overflow-x: hidden; white-space: nowrap; ) to maintain a clean format, and I would like the user to be able to see the full text if they choose to hover over a given cell. datatable(df, class="compact", selection="none", rownames=F, colnames=NULL, options=list(dom="t", pageLength=10 ), escape=F) Could you try this: datatable(head(iris), options=list(initComplete = JS("function(settings) {var table

I have a table with 5 cols and 1st column as character and other four as numeric. I am using DT Data Table to display the same in Shiny App. Now, I need to compare each of the four cols for each row and color code the row cell which has maximum value . Looking for ways to do the same. Had a look on this link as well StylingCells but all the cols are numeric here. Code entity <- c('entity1', 'entity2', 'entity3') value1 <- c(21000, 23400, 26800) value2 <- c(21234, 23445, 26834) value3 <- c(21123, 234789, 26811) value4 <- c(27000, 23400, 26811) entity.data <- data.frame(entity, value1, value2,
