row selection reactive variable needed for shiny app

[sanjmeh]

Prework

couldn't find any similar request in the issue list

Proposal

There is a DT package in R that is adopted from JS datatable package. This means a lot of its features are hidden and have to be passed through nested list(), which is very hard to remember. The only reason we still use DT package is the input$tabname_rows_selected reactive variable that is not available in gt (as yet).

I suggest gt package to also allow row selection to be detected in a shiny app as an input$.. variable. Then gt would be a compelling replacement of the DT package.

Could you provide an example? I’m not a heavy user of DT right now, so this would be helpful.

Here are some examples of the DT package reactive functionality inside a shiny app (min working code can also be seen)

Basically you can click on any row of the table and the row number is available to the shiny app. This is a powerful feature to provide interactivity and will add to the already powerful gt package with much needed reactivity.

Hi,

Is this type of functionality possible in an interactive gt table in Shiny?

Thanks

Not yet. But request @rich-iannone to consider it. It is indeed a powerful & much needed interactivity function missing in gt.

Can this be closed as a duplicate of #354?
