[mg82813] How to construct a vector whose elements are also vectors?

["Guofeng Zhang" <guofengzhang at gmail.com>]

Hi, there,
   I'd like to construct a vector whose elements are also vectors. I used
the following conmands:

Table[stat[i], {i, 1, 10}];
For[i = 1, i <= 10, (stat[i] = Array[0 &, {10, 2}]); i++];

Then I try
stat[1]
which yields
{{0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0,  0},
{0, 0}}

This seems okay. However, I don't know how to endow values to it, for
instance change the first {0, 0} to {1,0}.

Thank you for your time and help!
