I am trying to set the width of columns in a DataTable rendered in Shiny and am not able to implement it using the aoColumnDefs options. Has anyone tried this before ? My table has 1 text followed by 3 numeric columns. The numeric columns need to be narrower and the 1st column (text) wider.
output$result <- renderDataTable({
z <- as(dataInput(), "data.frame")
setnames(z, c("Rules", "Support", "Confidence", "StatDep"))
z
}, options = list(aLengthMenu = c(5, 30, 50), iDisplayLength = 5, bSortClasses = TRUE,
aoColumnDefs = list(sWidth = "50px", aTargets = list(1))))
Thanks,
** Update ** This seems to be working, but there might be other options to do this as well.
output$result <- renderDataTable({
z <- as(dataInput(), "data.frame")
setnames(z, c("Rules", "Support", "Confidence", "StatDep"))
z
}, options = list(aLengthMenu = c(5, 30, 50), iDisplayLength = 5, bSortClasses = TRUE,
bAutoWidth = FALSE,
aoColumn = list(list(sWidth = "150px", sWidth = "30px",
sWidth = "30px", sWidth = "30px"))
))
Try this
#OUTPUT - dtdata
output$table <- DT::renderDataTable({
data.frame(a=c(1,2,3,4,5),b=c("A","B","C","D","E"))
},
options = list(
autoWidth = TRUE,
columnDefs = list(list(width = '200px', targets = "_all"))
))
Sets the width of all columns to 200px.
To set width of selected columns, change targets
to a number or vector.
targets = c(1,3)
