Sorting for a JTable

[Ramkumar]

Hi,
Are there any code samples available which implements mulitple column sorting
on a JTable?That is, values based on the first column are sorted, then second
column is sorted without disturbing the sorting of the first.

eg:

1 11 12
2 22 22
1 12 11
2 21 23
1 10 11

will should be sorted into
1 10 11
1 11 12
1 12 11
2 21 23
2 22 22
if sorting is required on the first two columns

TIA,
Ramkumar
