See the project website for more details and live examples, and see below for important details on use in shiny apps.

An htmlwidgets implementation of Handsontable.js. Per the website:

Handsontable is a minimalist Excel-like data grid editor for HTML & JavaScript

This library was inspired by the shinyTable package. Most of the original functionality was preserved, and the htmlwidgets framework made it possible to leverage even more of the Handsontable.js functionality.

Note: With v7, handsontable went to a more restrictive license for commercial use. To avoid license violations for existing users, rhandsontable will not update handsontable beyond v6.2.2. This may change in the future if a way is found to manage multiple handsontable versions.

See the vignette for detailed examples and links to shiny apps.

To install from CRAN use

install.packages("rhandsontable")

For the latest development version use

devtools::install_github("jrowen/rhandsontable")

A simple example

library(rhandsontable)

DF = data.frame(int = 1:10,
                numeric = rnorm(10),
                logical = TRUE,
                character = LETTERS[1:10],
                fact = factor(letters[1:10]),
                date = seq(from = Sys.Date(), by = "days", length.out = 10),
                stringsAsFactors = FALSE)

# add a sparkline chart
DF$chart = sapply(1:10, function(x) jsonlite::toJSON(list(values=rnorm(10))))
                                                    
rhandsontable(DF, rowHeaders = NULL) %>%
  hot_col("chart", renderer = htmlwidgets::JS("renderSparkline"))

A more involved shiny example

shiny::runGitHub("rhandsontable", "jrowen", subdir = "inst/examples/rhandsontable_corr")

Important note on shiny use: The htmlwidgets package creates widgets as shiny output bindings. The rhandsontable package also attempts to expose the table as a pseudo shiny input binding using handsontable change events (see here for the supported events). This means the table (e.g. hot) can be accessed in shiny using either input$hot or output$hot, but these values may not be in-sync. The timing of updates will depend on the particular reactive path followed by your shiny application.

Since the widget is not currently able to use the standard shiny input binding functionality, you will need to explicitly call the hot_to_r function to convert the handsontable data to an R object.

Two additional inputs are also enabled, input$hot_select and input$hot_comment, which will fire when a cell selection or a comment changes, respectively (if you would like to see more options, please post an issue or create a PR).

This functionality is still evolving, so please don't hesitate to share suggestions and PRs.

You can’t perform that action at this time.
