Copying and pasting from Google docs and sheets is your easiest bet.
You can paste an Embed link from Google Sheets (found in Sharing options), and it will display the sheet and also refresh with updates as the sheet is updated in Google. As I've done here with the ITB Cycle Calendar.
You can also copy paste direct from a Google Doc and it will retain your formatting.

However, if you want to delete it you need to go into Source and select all the html for the table and delete it.
