Need a hand. Please?

i have a script in sh. with awk, e.g. want to list all the contents of a subdirectory an a tabular way.
ej: outoput
directory1
subdirectory1 subdirectory2 subdirectory3
file1 filen file2 filez
file2 ... filen+1 filex filey
..
filex

Ive got ion awk but the list output is vertically.
How can i do That.

Tabular, as in, all on one enormous line?
