How to convert row into column.I have following result set.

UserID  VendorName  QuestionText AnswerText
1         KK         abc1         ans1
1         KK         abc2         ans2
1         KK         abc3         ans3
2         JJ         abc1         ans2
2         JJ         abc2         ans3
2         JJ         abc3         ans1   

OUTPUT should be:

UserID VendorName   abc1    abc2   abc3
1             KK    ans1    ans2   ans3
2             JJ    ans2    ans3   ans1
