1 2 3 4 5 6 7 8 9 10 11 12 2 4 6 8 10 12 14 16 18 20 22 24 3 6 9 12 15 18 21 24 27 30 33 36 4 8 12 16 20 24 28 32 36 40 44 48 5 10 15 20 25 30 35 40 45 50 55 60 6 12 18 24 30 36 42 48 54 60 66 72 7 14 21 28 35 42 49 56 63 70 77 84 8 16 24 32 40 48 56 64 72 80 88 96 9 18 27 36 45 54 63 72 81 90 99 108 10 20 30 40 50 60 70 80 90 100 110 120 11 22 33 44 55 66 77 88 99 110 121 132 12 24 36 48 60 72 84 96 108 120 132 144
Getting just the top half, and some labels, requires a bit more work. Text alignment varies with implementation so the numbers will need some tweaking:
⎕←(' ×',2↑' '),4 0⍕⍳12⋄{⎕←((4 0⍕⍵),⊂1(4×(⍵-1))⍴' '),4 0⍕(⍵-1)↓(⍵×⍳12)}¨⍳12
After printing the table, GNU APL will will output the value of the expression that produced it, so in addition to adjusting the header spacing this solution uses ⍬⊣ to throw that value away.
⎕←(' ×',4↑' '),4 0⍕⍳12⋄⍬⊣{⎕←((4 0⍕⍵),⊂1(4×(⍵-1))⍴' '),4 0⍕(⍵-1)↓(⍵×⍳12)}¨⍳12
- Output:
× 1 2 3 4 5 6 7 8 9 10 11 12 1 1 2 3 4 5 6 7 8 9 10 11 12 2 4 6 8 10 12 14 16 18 20 22 24 3 9 12 15 18 21 24 27 30 33 36 4 16 20 24 28 32 36 40 44 48 5 25 30 35 40 45 50 55 60 6 36 42 48 54 60 66 72 7 49 56 63 70 77 84 8 64 72 80 88 96 9 81 90 99 108 10 100 110 120 11 121 132 12 144

Functional composition
As an alternative to iteration, we could also write the top level more declaratively, composing a solution from a set of generic functions.

Since the standard text output is poorly suited to this kind of formatted data, this example is implemented by writing to the screen buffer using the small font. Also, the limits were adjusted to 10x8 to make the table fit the screen.

The table consumes every one of the 1000 cells in a 40-column display, and even so has to cheat a little to fit 10x10=100 into the table. It uses the INSERT character (CHR$(148)) to push characters over to the right after printing them without triggering a scroll that would push the top line off the screen.

BQN
Table formats a multiplication table for any given n. The result is a character array and can be printed with •Out˘. The overall structure is to build a 3-by-3 array of parts, then put them together with a two-dimensional join (∾).
Table ← {
m ← •Repr¨ ×⌜˜1+↕𝕩 # The numbers, formatted individually
main ← ⟨ # Bottom part: three sections
>(-⌈10⋆⁼𝕩)↑¨⊏m # Original numbers

Traditional approach
The usual style is to write whole lines at a go, traditionally to fast lineprinters. Producing a tabular layout is easy (four characters per field to allow room to print 144 with a space separator), the difficulty lies in having blank parts at the start of the line followed by results. Having results followed by blanks is normal. The simplest way to achieve this would be to have a CHARACTER*4 function IFMT4(n) that returns four spaces for n <= 0, otherwise the digits, similar to the above example. But the plan is to write a line of such function calls at a go (with n = 0 for unwanted results), and alas, very few Fortran implementations allow recursive use of the formatted I/O system - here one level would be inside the function to produce the result for N > 0, and the other is the original WRITE statement that invokes the function.
So instead, write the table by first writing a line to a CHARACTER variable then blanking out the unwanted part.
Cast forth a twelve times table, suitable for chanting at school.
INTEGER I,J !Steppers.
CHARACTER*52 ALINE !Scratchpad.
WRITE(6,1) (I,I = 1,12) !Present the heading.
1 FORMAT (" ×|",12I4,/," --+",12("----")) !Alas, can't do overprinting with underlines now.
DO 3 I = 1,12 !Step down the lines.
WRITE (ALINE,2) I,(I*J, J = 1,12) !Prepare one line.
2 FORMAT (I3,"|",12I4) !Aligned with the heading.
ALINE(5:1 + 4*I) = "" !Scrub the unwanted part.
3 WRITE (6,"(A)") ALINE !Print the text.
END !"One one is one! One two is two! One three is three!...
Output in the same style as above, with underlining unavailable: those who have used a lineprinter's overprint facility to properly underline find the flabby modern requirement of a second line vexing, but, few output devices support underlining in so easy a way.
×| 1 2 3 4 5 6 7 8 9 10 11 12 --+------------------------------------------------ 1| 1 2 3 4 5 6 7 8 9 10 11 12 2| 4 6 8 10 12 14 16 18 20 22 24 3| 9 12 15 18 21 24 27 30 33 36 4| 16 20 24 28 32 36 40 44 48 5| 25 30 35 40 45 50 55 60 6| 36 42 48 54 60 66 72 7| 49 56 63 70 77 84 8| 64 72 80 88 96 9| 81 90 99 108 10| 100 110 120 11| 121 132 12| 144
Going to the trouble of preparing results, and then blanking some might seem a little too crude. An alternative would be to use a different FORMAT statement for each line of output. But, a collection of a dozen output statements hardly represents a programming solution. Instead, create and then use the text of FORMAT statements, as follows. Notice that there are no reserved words in Fortran.
Cast forth a twelve times table, suitable for chanting at school.
INTEGER I,J !Steppers.
CHARACTER*16 FORMAT !Scratchpad.
WRITE(6,1) (I,I = 1,12) !Present the heading.
1 FORMAT (" ×|",12I4,/," --+",12("----")) !Alas, can't do overprinting with underlines now.
DO 3 I = 1,12 !Step down the lines.
WRITE (FORMAT,2) (I - 1)*4,13 - I !Spacing for omitted fields, count of wanted fields.
2 FORMAT ("(I3,'|',",I0,"X,",I0,"I4)") !The format of the FORMAT statement.
3 WRITE (6,FORMAT) I,(I*J, J = I,12) !Use it.
END !"One one is one! One two is two! One three is three!...
The output is the same, so instead, here are the generated FORMAT texts:
(I3,'|',0X,12I4) (I3,'|',4X,11I4) (I3,'|',8X,10I4) (I3,'|',12X,9I4) (I3,'|',16X,8I4) (I3,'|',20X,7I4) (I3,'|',24X,6I4) (I3,'|',28X,5I4) (I3,'|',32X,4I4) (I3,'|',36X,3I4) (I3,'|',40X,2I4) (I3,'|',44X,1I4)
A zero count for spacing (the 0X, due to there being no omitted results on the first line) was possibly a weak point, but if not handled, the fallback position would have been to arrange that instead of 12I4 format, the first would be 1X,I3.
Some fortrans offer an extension to FORMAT statements, whereby a variable can appear in place of an integer constant, thus instead of say FORMAT (12I4) there could be FORMAT (<n>I4) for example. Then, during the interpretation of the FORMAT text, the current value of variable n would be accessed. Note that this is on-the-fly:
READ(in,"(I2,<N>I4)") N,(A(I),I = 1,N)
would read N as a two-digit integer, and, as the READ statement executes further, use that value of N both in the FORMAT text's interpretation and in the further processing of the READ statement.

Based on the above code but with a slight modification as VAX FORTRAN doesn't allow zero width fields in a format statement. The number of rows and columns can also be altered by modifying the value of K which must be in the range 1 - 25.

Rather more changes are needed to produce the same result, in particular we cannot modify the format specifier directly and have to rely on overlaying it with an integer array and calculating the ASCII values needed for each byte we need to modify. Nested implicit DO loops are allowed, but not used as it isn't possible to compute K on the fly so we have to calculate (and store) the results for each row before printing it. Note also that the unit numbers for the output devices are different and when using Hollerith strings to define values in a DATA statement the size of each string must match the size of the data type.

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).
Java
public class MultiplicationTable {
public static void main(String[] args) {
for (int i = 1; i <= 12; i++)
System.out.print("\t" + i);
System.out.println();
for (int i = 0; i < 100; i++)
System.out.print("-");
System.out.println();
for (int i = 1; i <= 12; i++) {
System.out.print(i + "|");
for(int j = 1; j <= 12; j++) {
System.out.print("\t");
if (j >= i)
System.out.print("\t" + i * j);
}
System.out.println();
}
}
}
- Output:
1 2 3 4 5 6 7 8 9 10 11 12 ---------------------------------------------------------------------------------------------------- 1| 1 2 3 4 5 6 7 8 9 10 11 12 2| 4 6 8 10 12 14 16 18 20 22 24 3| 9 12 15 18 21 24 27 30 33 36 4| 16 20 24 28 32 36 40 44 48 5| 25 30 35 40 45 50 55 60 6| 36 42 48 54 60 66 72 7| 49 56 63 70 77 84 8| 64 72 80 88 96 9| 81 90 99 108 10| 100 110 120 11| 121 132 12| 144
JavaScript
Unicode output
The following example works with any (modern) JavaScript runtime:
function timesTable(){
let output = "";
const size = 12;
for(let i = 1; i <= size; i++){
output += i.toString().padStart(3);
output += i !== size ? " " : "\n";
}
for(let i = 0; i <= size; i++)
output += i !== size ? "════" : "╕\n";
for(let i = 1; i <= size; i++){
for(let j = 1; j <= size; j++){
output += j < i
? " "
: (i * j).toString().padStart(3) + " ";
}
output += `│ ${i}\n`;
}
return output;
}
- Output:

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]

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).
Functional
We can define a multiplication table string first in terms of a list comprehension (mulTable function),
and then again, for comparison, as an equivalent list monad expression (mulTable2 function):
'''Multiplication table
1. by list comprehension (mulTable ),
2. by list monad. (mulTable2)'''
from itertools import chain
# mulTable :: Int -> String
def mulTable(n):
'''A multiplication table of dimension n,
without redundant entries beneath
the diagonal of squares.'''
# colWidth :: Int
colWidth = len(str(n * n))
# pad :: String -> String
def pad(s):
return s.rjust(colWidth, ' ')
xs = enumFromTo(1)(n)
return unlines([
pad(str(y) + ':') + unwords([
pad(str(x * y) if x >= y else '')
for x in xs
]) for y in xs
])
# mulTable2 :: Int -> String
def mulTable2(n):
'''Identical to mulTable above,
but the list comprehension is directly
desugared to an equivalent list monad expression.'''
# colWidth :: Int
colWidth = len(str(n * n))
# pad :: String -> String
def pad(s):
return s.rjust(colWidth, ' ')
xs = enumFromTo(1)(n)
return unlines(
bind(xs)(lambda y: [
pad(str(y) + ':') + unwords(
bind(xs)(lambda x: [
pad(str(x * y) if x >= y else '')
])
)
])
)

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 12A 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.
