Look up to the last non-blank cell in column 1 to concatenate with a value in column 2

What can I do to use the last non-blank cell of Column 1 to concatenate with the value in Column2? For example:

Can you just fill in the blanks with the value from the previous cell above?

Highlight column 1, click Edit - goto - special - blanks - OK
Press =
Press UP Arrow Key
Press CTRL + ENTER

Then you can just use simple concatenate formula.

Try...

D2, just enter and copy down:

=LOOKUP(REPT("z",255),$A$1:A2)&"_"&B2
