Callout Box/Edit Window from table

I am trying to make a call out box or a new window appear from a table I have in my MainComponent.
So far I have created a column which has an edit button for each row. The call out box would then be able to edit the data in that row.

Does anyone have any idea what the best method for doing this might be? All help is apreciated!

This is a bit of a vague question. Are you asking about how to make a dialog? or how to send the data from the table to the dialog? or?

I am trying to workout how to make the call outbox from the button based in the table. I can make the call out box but only from buttons based in my main component.
