Say that I have a table of People, and these people have a Country column and a unique Primary Key. It's a demographics table, so these are the only things I care about; what Country and how many unique people are tied to that country.
I am thus only ever likely to SELECT WHERE or ORDER BY the Country column; a clustered index on the Primary Key doesn't do me any good, I'm not accessing this data by PK, I'm accessing it by this other column. Since I can only have one clustered index on a table, declaring my PK as Clustered would prevent me from using a Clustered Index on Country.
Your instinct may be to yell and get angry. It’s natural. But just because it’s “natural” doesn’t mean it’s a good idea.

The Rules of the Grid:
Columns must be the immediate child of a Row.
Rows are only used to contain Columns, nothing else.
Rows should be placed inside a Container.
