render_hot: Function to (re)render an existing rhandsontable
In dqshiny: Enhance Shiny Apps with Customizable Modules

Description Usage Arguments Value Author(s) Examples

Function to send a message to js to render an existing rhandsontable object. E.g. needed when handsontable is used with stretchH = 'all' and a select callback to choose a dataset and present its data to the user. Handsontable won't properly render the table if the height of the page increases due to some visibility changes and a scroll bar appears.

1	render_hot(id)

`id`	id of the hot object
