I have a pivot table already created; the data source is the next worksheet.

Since then I added some data outside the data source by addicg some rows of
data to the bottom of the data source.

Can the data source for the existing pivot table be change to include these
added rows (if so, how) or do I need to delete this pivot table and create a
new pivot table via the wizard to include all new data?

Thanks in advance for help.
