Sort column beginning with blank?

[Pete]

Want to sort a column by number. Numbers unclude blanks, then, 0-9.

Need to sort the column beginning with the blank, then from 0 through 9. (So, blank comes before zero.) Is there a way to do this?
TIA for any ideas.

Came up with an answer:
I created a helper column; and any value that should return a blank, instead obtains a value of -.5 (negative point 5). Then sort, so that it would show up on the proper sort order.
Using conditional formatting to display any value less than zero in a white font, in effect displays the blank.
Thanks for any thought put into this.
