Here is an example with a curve over a small field GF(17)
$=\Bbb F_{17}$ having order $23$ and exactly one generator:
$$
E \ :\ y^2 = x^3 +3x+5\qquad\text{ over }F=\Bbb F_{17}\ .
$$
Then every non trivial point is a generator, let $P=(2,6)\in E(F)$ be our choice for the table.
The table can be obtained via:
sage: P = E.point( (2, 6) )
sage: print E.order(), P.order()
23 23
sage: for k in range(23):
....: Q = k*P
....: print "%2s | %s" % (k, Q.xy() if Q else 'ZERO')
....:
0 | ZERO
1 | (2, 6)
2 | (5, 3)
3 | (11, 3)
4 | (6, 1)
5 | (1, 14)
6 | (10, 7)
7 | (9, 8)
8 | (4, 8)
9 | (12, 1)
10 | (16, 1)
11 | (15, 12)
12 | (15, 5)
13 | (16, 16)
14 | (12, 16)
15 | (4, 9)
16 | (9, 9)
17 | (10, 10)
18 | (1, 3)
19 | (6, 16)
20 | (11, 14)
21 | (5, 14)
22 | (2, 11)
