Register a DT DataTable Component — register

register_dt registers a DT datatable for linking with other components.

Usage

register_dt(
  session,
  registry,
  dt_output_id,
  data_reactive,
  shared_id_column,
  click_handler = NULL
)

Arguments

session: 'shiny' session object. The session from the module where the DT is used. This could be global session in non-modular apps.
registry: A link registry created by create_link_registry()
dt_output_id: Character string: the outputId of your DT::DTOutput
data_reactive: Reactive expression returning the data frame for the table
shared_id_column: Character string: name of the ID column
click_handler: Optional function: custom click handler for row selection, must have args (map_proxy, selected_data, session), overrides all default behavior

Value

NULL (invisible). This function is called for its side effects of registering the component.

Examples

# \donttest{
  # Create a mock session for the example
  session <- shiny::MockShinySession$new()

  # Create a registry
  registry <- create_link_registry(session)

  # Sample reactive data
  my_data <- shiny::reactive({
    data.frame(
      id = 1:5,
      name = c("A", "B", "C", "D", "E"),
      value = 11:15
    )
  })

  # Register a DT component
  register_dt(session, registry, "my_table", my_data, "id")

  # Verify registration
  print(registry$get_components())
#> $`mock-session-my_table`
#> $`mock-session-my_table`$type
#> [1] "datatable"
#> 
#> $`mock-session-my_table`$shared_id_column
#> [1] "id"
#> 
#> $`mock-session-my_table`$config
#> $`mock-session-my_table`$config$click_handler
