Suppose I have an arbitrary table, eg

   zz
1  2  3  4  5
2  3  1  8 10
3  1  2 12 15
4  8 12  6  2
5 10 15  2  7

what's a slick way of displaying it boxed and labelled, like this? ...

+-+-------------+
|s|0  1  2  3  4|
+-+-------------+
|0|1  2  3  4  5|
|1|2  3  1  8 10|
|2|3  1  2 12 15|
|3|4  8 12  6  2|
|4|5 10 15  2  7|
+-+-------------+

Sorry to be lazy. It would do me good to work it out for myself, but
I'm pressed for time. Needed for APWJ. The best I can come up with so
far is this:

s=: 4 : '(<x;<y) { zz'
s table i.5
...
