end
The above example is a somewhat exaggerated example of contractions. In both cases 'every' is used to force all alternatives including row labels, column headings, content, line terminators. The upper triangle is produced by embedding an 'if' expression inside the object of an 'every' (normally an error prone construct which would malfunction if not carefully separated from the generators for 'i' and 'j' - an all too tempting possibility once you get into this mind set.)

That said, note that */~ is the core primitive used to construct a multiplication table and this is a general technique so that, for example, +/~ would make an addition table. The rest is just to make it look pretty (and to blank out the lower triangle -- we use a less than or equal table (<:/~) to control that, and format zeros as spaces to blank them out).

[edit] MOO
This quick example is designed to demonstrate raw MOO. In other words it does not use any of the helper functions available in popular DBs such as LambdaMOO.
@verb me:@tables none none none rxd
@program me:@tables
player:tell(" | 1 2 3 4 5 6 7 8 9 10 11 12");
player:tell("-------------------------------------------------------------------");
for i in [1..12]
line = ((i < 10) ? " " | " ") + tostr(i) + " | ";
for j in [1..12]
if (j >= i)
product = i * j;
"calculate spacing for right justification of values";
if (product >= 100)
spacer = "";
elseif (product >= 10)
spacer = " ";
else
spacer = " ";
endif
line = line + " " + spacer + tostr(product);
else
line = line + " ";
endif
endfor
player:tell(line);
endfor
.
LambdaMOO string utilities version:
@program me:@tables
player:tell(" | 1 2 3 4 5 6 7 8 9 10 11 12");
player:tell($string_utils:space(67, "-"));
for i in [1..12]
line = " " + $string_utils:right(i, 2) + " | ";
for j in [1..12]
line = line + " " + ((i > j) ? " " | $string_utils:right(j*i, 3));
endfor
player:tell(line);
endfor
.
Output:

The above works with Python 3.X, which uses Unicode strings by default.
Declaring a file type of UTF-8 and adding a u to all string literals to transform them into Unicode literals would make the above work in Python 2.X.
(As would using ASCII minus, plus, and pipe characters: "-", "+", "|"; instead of the non-ASCII chars used to draw a frame).
[edit] R
An ugly one line solution:
upper.tri(1:12 %o% 1:12, diag = TRUE) * 1:12 %o% 1:12
... and a much prettier one:
multiplication_table <- function(n=12)
{
one_to_n <- 1:n
x <- matrix(one_to_n) %*% t(one_to_n)
x[lower.tri(x)] <- 0
rownames(x) <- colnames(x) <- one_to_n
print(as.table(x), zero.print="")
invisible(x)

[edit] Ursala
It's no more difficult to express the general case than the size 12 case, so a table generating function parameterized by the size is used.
#import std
#import nat
table "n" =
~&plrTS(
~&xS pad` @xS <'x ','--'>-- --' | '*hS %nP* nrange/1 "n",
^CthPiC(`-!*h,~&) mat` *xSSK7 pad` *K7ihxPBSS (~&i&& %nP)** nleq&&product**iiK0lK2x nrange/1 "n")
#show+
main = table 12
A better way of using Ursala to make tables would be with the tbl library included with
the standard package, which can generate LaTeX code for arbitrary heading hierarchies and typesetting options, but here it is in ASCII art.
