Table SQL preview
You can see the SQL representation of your table, it includes columns, indexes, foreign keys, etc. Actually this is SQL-code to be executed while generating database.
To see SQL representation of the table, double click on the table symbol and Table Editor will appear. Go to the Preview tab. SQL representation is shown using standard Text Editor. So you can save to file, copy to clipboard, print SQL-code and so on.
