dt

问题 I am looking to color format each numeric column so that it shows a blue range bar depending on the range of each column. Here is a photo on what I am trying to achieve. #Here is the the table I have so far. #I am adding filters to the columns. This works great library(DT) library(magrittr) df = datatable(iris, filter = 'top', options = list(pageLength = 5, autoWidth = TRUE)) #I try to add the blue bars here to the first 2 numeric columns df %>%formatStyle(names(df)[1:2], background =

问题 I'm trying to style the expand rows button available in DT. The styling is available here. The code I'm using for creating the datatable is- library(DT) datatable( cbind(' ' = '⊕', mtcars), escape = -2, options = list( columnDefs = list( list(visible = FALSE, targets = c(0, 2, 3)), list(orderable = FALSE, className = 'details-control', targets = 1) ) ), callback = JS(" table.column(1).nodes().to$().css({cursor: 'pointer'}); var format = function(d) { return '<div style=\"background-color:#eee

问题 I have a first DT table oTable with cell selection enabled. When the user click (select) a cell, that will generate another DT table nTable . Then, in nTable I want to insert a selectInput . The code below is a working example. Mostly adapted from this post. Problem: When nTable is regenerated, the connection (binding?) with shinyValue is somehow broken. Step to reproduce the problem: launch the app. select top left cell (e.g. Sepal.Length=5.1). In fact, select any cell will also work. In the

问题 I'm using R's DT in a FlexDashboard. I have the export buttons working, but I'd like to be able to make the exports export only the data that is either selected via rows or when using the DT search function. I've looked at the DT manual, but it hasn't clarified how I'd go about it. datatable( dept_table, rownames = FALSE, extensions = "Buttons", options = list( searching = TRUE, pageLength = 200, scrollX = TRUE, scrollY = TRUE, dom = "BRSpfrti", buttons = c('copy', 'csv', 'excel', 'pdf',

问题 Just like most people, time date format is also not my favorite topic in R, and is once again giving me more trouble than I bargained for. In follow-up of this question: SO I got rid of the 'T' and 'Z' with 'toLocaleString' but now my datatable is showing times in AM and PM, while I just want to see the original 24h times. I'm running the app in google chrome, and my output looks like this at the moment: library(shiny) library(DT) data <- structure(list(DATUM = structure(c(1490738402,

问题 I would like to ask if it is possible to add a column with tickboxes in a DT datatable. I tried to use rep(TRUE,5) which works for rhandsontable but not for DT . library(DT) datatable( data.frame(Sel. = rep(TRUE,5), Label=paste("Test",as.integer(1:5)), Marg=rep(5), Avail.=as.integer(rep.int(5,5)), Sel =as.integer(rep.int(5,1)), stringsAsFactors = FALSE)) 回答1: Yes, it's possible. We can use the datatable extension Select for that (see here for details). Here is a minimal RMarkdown example: ---

问题 I've read the DT.pdf doc and searched, but it seems like different colors is not supported by DT package. How could I achieve the effect shown in the image link below? Thanks! example: different colors for positive and negative values 来源： https://stackoverflow.com/questions/32830382/shiny-dt-stylecolorbar-different-color-for-positive-and-negative-values

问题 I have a dataset: ID Value 102 306 41 800 101 783 105 193 myID 334 I would like to draw this up as a datatable where only the row with 'myID' is coloured orange and the rest of the table is blue. Having looked at the helper functions and other examples, it seems that I should be using styleEqual. However, I don't know what the values in my other rows are, and also they will change dynamically. I tried using datatable(tableData) %>% formatStyle(0, target= 'row',color = 'black', backgroundColor

问题 I am using DT::datatable() to visualize tables in a R markdown file. # R markdown file library(DT) ```{r viewdata} # this is an example but my actual dataset has 10000 rows and 100 columns var.df <- data.frame(x = rnorm(1:10000), y = rnorm(1:10000),...) DT::datatable(data = var.df) ``` When I run this code, I get a warning and the resulting HTML is very slow to load: DT::datatable(var.df) Warning message: In instance$preRenderHook(instance) : It seems your data is too big for client-side
