cannot undersyand the whole code

Hello,

According to the Guide manual this can be a way to make a table widget:

initialize
     | list |
     super initialize.
     "Create a collection of sightings data."
     list := TwoDList
         on: #('Vulcans' 188 173 192 'Romulans' 26 26 452) copy
         columns: 4
         rows: 2.
     sightingsTable := SelectionInTable with: list.
     "Create a table interface and load it with the sightings."
     tableInterface := TableInterface new
         selectionInTable: sightingsTable.

     tableInterface columnWidths: #(100 40).

I understand that tableInterface is the name which is typed in the
aspect of the table widget.
But where does sightinsTable comes from.

What class is the #initialize method in?


Check its class hierarchy for an instance variable named 'sightingsTable'
