How can I have paragraph spacing for normal paragraphs, but no paragraph spacing within tables?

After a lot of trial and error I have found a configuration that so far seems to work pretty well:

Standard style: 10pt before, 10pt after

Table style: 'Auto' before, 'Auto' after

And the result:

Assuming you haven't tried this already, consider creating a separate paragraph style for table Paragraphs. Apply it to the first one, others should follow, or apply globally to the table.
