is it practical to use renderplot or renderdatatable with showModal & modalDialog ?

Do you mean showing a plot/table with a modal?

What's your definition of "practical"? What are you trying to achieve?

It's certainly possible, and may even be a good idea for your situation.

Thanks, 'practical' means capability of show a big datatable or a plots with showModal & modalDialog without causing other problems like cashing the app or freezing the app.

It should be ok, yes. Have you tested it (e.g. tried displaying a very large datatable in a modal)?
