```I tried your problem under both Versions 4.0 and 4.1 and could not replicate
the situation you report. I used the same two lines that follow:

In[1]:=
x = Round[100*Table[{i, i/5, i/3}, {i, 1, 20}]]/100.
Out[1]=
{{1., 0.2, 0.33}, {2., 0.4, 0.67}, {3., 0.6, 1.}, {4., 0.8, 1.33}, {5., 1.,
1.67}, {6., 1.2, 2.}, {7., 1.4, 2.33}, {8., 1.6, 2.67}, {9., 1.8,
3.}, {10., 2., 3.33}, {11., 2.2, 3.67}, {12., 2.4, 4.}, {13., 2.6,
4.33}, {14., 2.8, 4.67}, {15., 3., 5.}, {16., 3.2, 5.33}, {17., 3.4,
5.67}, {18., 3.6, 6.}, {19., 3.8, 6.33}, {20., 4., 6.67}}
In[2]:=
Export["table.txt", x, "Table"]
Out[2]=
"table.txt"

Of course the results appear in the corresponding directories Math4.0 and
Math4.1, respectively. Still, opening in Excel File|Open|..... yields in
both cases the 20 x 3 table|

1 0.2 0.33
2 0.4 0.67
3 0.6 1
4 0.8 1.33
5 1 1.67
6 1.2 2
7 1.4 2.33
8 1.6 2.67
9 1.8 3
10 2 3.33
11 2.2 3.67
12 2.4 4
13 2.6 4.33
14 2.8 4.67
15 3 5
16 3.2 5.33
17 3.4 5.67
18 3.6 6
19 3.8 6.33
20 4 6.67
