Userpoints : How to alter myuserpoints table

I am using userpoints module. In that when i click the 'My Score' link i am viewing a table with list of points.

There are 6 headers and 6 rows displaying. In that table i need only 3 headers and 3 rows to display.

For example: As of now:
Points - Approved - Date - Operation - Category - Description

What i need to display:
Points - Date - Description

How can i achieve this ?

Any help will be thankful and grateful...

Thanks in advance..
