It would be very useful in some cases to be able to see columns statistics (the same information available in the Data analysis flyout) from the "old" and "new" data. This would help to make a decision on which columns should be matched when the columns names from the previous and new data tables are not helping to match the columns.
The column widths can not be adjusted, when the column names are "too long", the full name can not be displayed directly. Needing to hover each column is not efficient. Being able to resize the column name width (both From current data and From new data) would be helpful.
See attached visual proposal.
Thank you for your consideration.
Kind regards,
Xavier
Also, being able to sort by name and having a filter box like almost everywhere else would be very beneficial. No fun to go through 100 unsorted entries in that too tiny boxes.
Thanks again for a great idea and description Xavier. Let's discuss this in a meeting shortly.
