Table layout
The -t option aligns the words on a grid. The end-of-line characters, if any, are ignored.
Here the entry consists of lines each containing a single word:
... daren elvis ... maury tully ...
Simplest use (-t alone):
smenu -s dave -t -n 10
Only on 3 columns:
smenu -s dave -t 3 -n 10
On 3 columns but using all the available terminal width
smenu -s dave -t 3 -w -n 10
