Hello then, for our viewers who have been using grouping and ungrouping, you would have also noticed as you group the different columns and rows, you also get two buttons associated with every one set of grouping in terms of column. And similar for rows. Now what are these? If I click on this digit one, it summarizes all the group columns into a collapsible form. If I click on two, it just expands back to the full scenario. Same goes for the row based grouping.
If I click on to all the cities in front of me, click on one it summarizes back to its compact form.
