Word table: How do I know which cells have been merged?

[Debbe]

I received a table that merged cells. I need to be able to sort, but can't
because of the merged cells. How can I tell which cells are merged? The
table is huge, over 200 pages.

Do you find it so? I find that Excel won't sort if any cells have ever been
merged, even if the rows from which they came no longer exist.
