    Thanks for another great video. I always prefer to do as much work in the nested tables as possible, it seems quicker and has the great bonus that it dicourages the guys who think they know what they are doing from editing and breaking your query as they see all the brackets and indentations and can't work out what part of the code they want to change.

    New viewer / subscriber, loved the use of record, I've always just piled transformations on top of each other, putting them in the form of a record is so much easier to read.

    I appreciate your “get right to business” method of teaching. This video was mind-blowing! When I navigated to “Like” the video, I discovered I was not yet a subscriber?!?! Oops! I am subscribed now, because I always learn something new from you. Also, I see musical instruments behind you. I’m compelled to support a fellow musician and Power Query teacher-two of my favorite pastimes! Thank you!!

    Great video! Thanks for all your content! I've been looking for a way to pull in a value from the 'outer table' into my nested table for hours. All examples seem to have to add a new column to the outer table first. Is there a way to add the "PortfolioAndSource" column in your example directly to the nested table? - Best.

    In that final transformation step to populate Portfolio and Source in the inner table, you did that by adding a column in the outer table. Is it possible to instead use TransformColumns on the outer table, so that you don't need to add a column to it in order to extend the inner table? I had a go at this but I couldn't get the syntax to work as Name.1 and Name were not in scope.
