How do I find the first row in a range?

You can get the first row (i.e. the starting row number) in a range with a formula based on the ROW function. In the example shown, the formula in cell F5 is: = MIN(ROW( data )) where data is a named range for B5:D10.

What is the difference between firstrow and lastrow?
