dt

问题 In my shiny app I'm creating a datatable using the DT package. I have column filters enabled, however, I want to hide the row of filter boxes. I have separate shiny widgets outside of the datatable which will act as the filters and pass them to the datatable through the searchCols option. Disabling column filters would hide the row of filter boxes but then the searchCols option doesn't work. When I run the app and inspect the elements, I see that the row I want to delete is called < tr role=

问题 This question already has answers here : R Shiny set DataTable column width (2 answers) Closed 9 months ago . I am building a Shiny dashboard and one panel on the dashboard is a DataTable. Below is my code: output$table = DT::renderDataTable(b1, selection = 'single') The width of columns in the data table is now adjusted with the width of column name. However, some cell values are text, and those text are squeezed to display in multiple lines as they are longer than the column names. I am

问题 Using this code to format the rows in my datatable rowCallback = DT::JS( 'function(row, data) { // Bold cells for those >= 5 in the first column if (parseFloat(data[0]) >= 5.0) $("td", row).css("background", "red"); }' ) I would like to alter this code so that rather than the static "5.0" value, highlighting is based on an an input$ value. So that users could click on a point on the chart, and rows with that value would be highlighted in the data table. But substituting input$click for 5

问题 I opened a thread about how to add range bars in a datatable here:Programmatically color format numeric columns in a datatable. However instead of fitting the ranges based on the whole data frame, I would like to format based on the range of each individual column. I figured out some code that works, however, it is most definitely daunting and not programmatic. library(magrittr) library(DT) # Specify numeric columns foo <- sapply(iris, is.numeric) datatable(iris, filter = 'top', options =

问题 I have a matrix M with positive values and negative values. I have another matrix X (dim(X) = dim(M)). I am trying to display X as a table in shiny app, using the DT package. I would like to display the matrix X with different colors conditioned by the values of M . It means: color1 in cells of X where M > 0 (X[M>0]) , color2 in cells of X where M<0 (X[M<0]) and color3 in cells of X where M == 0 (X[M == 0]) . The next code shows where I got stuck: X <- matrix(c(1:9), 3) M <- matrix(c(-3:2), 3

问题 I am trying to add pagination, search box and selector in my R Shiny app, but it doesn't work for now (I tried paging = TRUE and searching = TRUE, in options as you can see bellow but it doesn't work). Do you have any idea of what I should add? output$mytable1 <- DT::renderDataTable( DT::datatable( { plots.dfs()[[1]] }, caption = htmltools::tags$caption( style = 'caption-side: bottom; text-align: center;', 'Table 2: ', htmltools::em('This is a simple caption for the table.') ), extensions =

问题 my css skills are extremely limited but assuming the following example: sketch = htmltools::withTags(table( class = 'display', thead( tr( th(rowspan = 2, 'Species'), th(colspan = 2, 'Sepal'), th(colspan = 2, 'Petal') ), tr( lapply(rep(c('Length', 'Width'), 2), th) ) ) )) datatable(head(iris, 10), container = sketch, options = list( initComplete = JS( "function(settings, json) {", "$(this.api().table().header()).css({'background-color': '#000', 'color': '#fff'});", "}") )) How would I change

问题 When I run my Shiny app, the headers of my data tables get shifted to the left. See below.Say this table is on Tab A. The headers get aligned correctly when I click on a different tab (Tab B),then click on Tab A again. See below for the corrected headers. Any idea what's causing it? Below is a simplified version of my code. Thanks in advance! ui.R library("shinythemes") fluidPage(title = "Segmentation App", theme = shinytheme("spacelab"), navbarPage("Segmentation", id = "allResults", tabPanel

问题 I am developing a Shiny app using R 3.3.1, Shiny v. 1.2.0 and v. DT 0.5. One of the elements is an editable data table that spans multiple pages. After I make an edit the row in focus jumps to row #1 which kind of ruins the user experience. Here are the specific steps to reproduce this using the snippet below: Load the app Switch to page 2 of the data table Edit row 3, column 2: change Duh to Blue and press Tab Watch the current row jump to page 1 row 1. This would be easier to see if the

问题 I am trying to get a datatable (DT) to scroll to the proper row/line when hovering over a point on a map. I can do things like have the row be selected, but I cannot figure out how to make the datatable Y-scroll to the proper entry. I'm trying to do this without Paging, as my datatable uses subsets and is not overall that large. I'm doing this in R/Shiny/DT my javascript experience is 0. This post seems to have been trying to do the same thing, except that the example is one the initial table
