}
\arguments{
\item{data}{a data object (either a matrix or a data frame)}

\item{...}{arguments passed to \code{format}.}

\item{options}{a list of initialization options (see
\url{http://datatables.net/reference/option/}); the character options
wrapped in \code{\link[htmlwidgets]{JS}()} will be treated as literal
JavaScript code instead of normal character strings; you can also set
options globally via \code{\link{options}(DT.options = list(...))}, and
global options will be merged into this \code{options} argument if set}

\item{class}{the CSS class(es) of the table; see
\url{http://datatables.net/manual/styling/classes}}

\item{callback}{the body of a JavaScript callback function with the argument
\code{table} to be applied to the DataTables instance (i.e. \code{table})}

\item{caption}{the table caption; a character vector or a tag object
generated from \code{htmltools::tags$caption()}}

\item{filter}{whether/where to use column filters; \code{none}: no filters;
\code{bottom/top}: put column filters at the bottom/top of the table; range
sliders are used to filter numeric/date/time columns, select lists are used
for factor columns, and text input boxes are used for character columns; if
you want more control over the styles of filters, you can provide a list to
this argument of the form \code{list(position = 'top', clear = TRUE, plain
= FALSE)}, where \code{clear} indicates whether you want the clear buttons
in the input boxes, and \code{plain} means if you want to use Bootstrap
form styles or plain text input styles for the text input boxes}

\item{escape}{whether to escape HTML entities in the table: \code{TRUE} means
to escape the whole table, and \code{FALSE} means not to escape it;
alternatively, you can specify numeric column indices or column names to
indicate which columns to escape, e.g. \code{1:5} (the first 5 columns),
\code{c(1, 3, 4)}, or \code{c(-1, -3)} (all columns except the first and
third), or \code{c('Species', 'Sepal.Length')}}

\item{style}{the style name (\url{http://datatables.net/manual/styling/});
currently only \code{'default'} and \code{'bootstrap'} are supported}

\item{width}{Width/Height in pixels (optional, defaults to automatic
sizing)}

\item{height}{Width/Height in pixels (optional, defaults to automatic
sizing)}

\item{elementId}{An id for the widget (a random string by default).}

\item{fillContainer}{\code{TRUE} to configure the table to automatically fill
it's containing element. If the table can't fit fully into it's container
then vertical and/or horizontal scrolling of the table cells will occur.}

\item{autoHideNavigation}{\code{TRUE} to automatically hide navigational UI
when the number of total records is less than the page size.}

\item{selection}{the row/column selection mode (single or multiple selection
or disable selection) when a table widget is rendered in a Shiny app;
alternatively, you can use a list of the form \code{list(mode = 'multiple',
selected = c(1, 3, 8), target = 'row')} to pre-select rows; the element
\code{target} in the list can be \code{'column'} to enable column
selection, or \code{'row+column'} to make it possible to select both rows
and columns (click on the footer to select columns), or \code{'cell'} to
select cells}

\item{extensions}{a character vector of the names of the DataTables
extensions (\url{https://datatables.net/extensions/index})}

\item{plugins}{a character vector of the names of DataTables plug-ins
(\url{https://rstudio.github.io/DT/plugins.html}).  Note that only those
plugins supported by the \code{DT} package can be used here.}

\item{rownames}{\code{TRUE} (show row names) or \code{FALSE} (hide row names)
or a character vector of row names; by default, the row names are displayed
in the first column of the table if exist (not \code{NULL})}

\item{digits}{the desired number of digits after the decimal
    point (\code{format = "f"}) or \emph{significant} digits
    (\code{format = "g"}, \code{= "e"} or \code{= "fg"}).

    Default: 2 for integer, 4 for real numbers.  If less than 0,
    the C default of 6 digits is used.  If specified as more than 50, 50
    will be used with a warning unless \code{format = "f"} where it is
    limited to typically 324. (Not more than 15--21 digits need be
    accurate, depending on the OS and compiler used.  This limit is
    just a precaution against segfaults in the underlying C runtime.)

}
\description{
This function creates an HTML widget to display rectangular data (a matrix or data frame) using the JavaScript library DataTables, with a method for \code{desctable} objects.
}
\note{
You are recommended to escape the table content for security reasons (e.g. XSS attacks) when using this function in Shiny or any other dynamic web applications.

\examples{
library(DT)

# see the package vignette for examples and the link to website
vignette('DT', package = 'DT')

# some boring edge cases for testing purposes
m = matrix(nrow = 0, ncol = 5, dimnames = list(NULL, letters[1:5]))
datatable(m)  # zero rows
datatable(as.data.frame(m))

m = matrix(1, dimnames = list(NULL, 'a'))
datatable(m)  # one row and one column
datatable(as.data.frame(m))

m = data.frame(a = 1, b = 2, c = 3)
datatable(m)
datatable(as.matrix(m))

# dates
datatable(data.frame(
  date = seq(as.Date("2015-01-01"), by = "day", length.out = 5), x = 1:5
))
datatable(data.frame(x = Sys.Date()))
datatable(data.frame(x = Sys.time()))
