exporting an array


Hi,

I have a question on how to export a matrix. My code generates a
vector of dimension (200 X 1), and I define:

b = Table[b1[i] /. solution, {i, 1, 200}];

I want to assign counters to these values, and have 1,2,3,.....,200 as
the first column. Finally I want to export this (200 X 2) matrix to a
file. I tried the following but they don't work:

Export["file.txt", {i, 1, 2000}, b];
Export["file.txt", i, b];

I would appreciate it if anyone could suggest a way to do this.

Thanks
nt
