Tab instead of space:

  awk '{print $1 "\t" $NF}'

Left-justified first column:

  awk '{printf "%-16s\t%s\n", $1, $NF}'

Columnized output:

  awk '{print $1, $NF}' | column -t

`column -t` is easy to use and produces nicely aligned output. The
downside is that it buffers all input, so it's not always applicable.
